Encrypt Sign Form Fast

They aren’t, at least not in any of the practical encryption algorithms I’ve ever seen.True fast-growing functions like factorials and Ackermann (two of the simplest) share at least two properties that make them highly unsuitable for encryption in their bare form:They take a very long time to compute, and/orThey take too much space to represent intermediate results, much less the final answerNeither of those properties is conducive to use in real-life crypto code in supercomputers, much less desktop PCs and embedded IoT devices.That said, there’s at least one function I can think of that might be considered “fast-growing”—if the lighting is bad and you squint really hard.Modular exponentiation lies at the heart of the venerable RSA public key system, and while exponentiation itself is somewhat fast-growing, ME exploits certain mathematical identities to trade CPU cycles for a large reduction in required memory.The result: RSA encryption doesn’t take gigabytes of RAM, but it’s no speed demon either. This is why it’s usually relegated to “small jobs” like signing message digests, and encrypting keys for symmetric encryption algorithms like AES. The latter, using no fast-growing functions at all, channel the Speed Force in comparison.Q: Why are very fast growing functions important in encryption?

Software Engineer here.Hollywood gets our profession horribly comically wrong.I feel like there are 2 main things it gets wrong:The existence of God-like hackers who can break into any system in any required timeline given the right incentives.The use of fancy graphics, both in trying to root out a security bsignNow, and to taunt someone who you are hacking.The dream #1: Any software problem of any complexity can be solved in a matter of minutes if you just have enough urgency and the right super-hacker.A prime example of this expectation is in the movie Swordfish. Bad guys want Hugh Jackman to break a 128-bit encrypted password pronto. To put the pressure on, they hold a gun to his head promising to shoot him if not done in 60 seconds. Simultaneously and inexplicably, they have someone give him a blowjob.Somehow by concentrating really hard and typing really fast Jackman cracks the system within the ridiculous timeline!The reality #1: complex problems take time. Immense pressure doesn’t help, it just makes you flustered. Putting a gun to someone’s head and sucking their dick won’t make them suddenly able to crack a password on a secure website in 60 seconds.This is the equivalent of telling some muscle-bound guy in the moving business, “I’ve heard you’re one of the best and the fastest! To prove it to me, I’m going to need you to relocate this Super-Walmart and all of it’s inventory to a new location in 60 seconds! And if you don’t, I’ll slit your throat.” No sane person would even try to move the Walmart - they would fight or flee. If you saw this Walmart scenario as a scene in a movie and the guy went on to actually successfully move the Walmart in 60 seconds (while getting a blowjob) just by trying really hard, you would probably think that was so stupid, you would stop watching the movie. I wish people would start having the same reaction to these ridiculous hacking scenes so that Hollywood would eventually stop including them in movies.The dream #2: When trying to debug any sort of problem with your software, developers do that debugging through beautiful polished graphical interfaces that came out of thin air as if by magic. And hackers always announce “You’ve been hacked!” with a loud flashy graphic.Skyfall - some real-time visual of their network being hackedSkyfall - Hacker’s calling cardNCIS - Another common TV representation of hacking. If someone hacks into your system, you will see dozens of new windows pop up every second and inexplicable progress bars.Hackers - graphic of a system being hackedReality #2: Developers who are debugging a problem like a security bsignNow rarely have any graphics to look at. We generally look at text from log files. If we’re lucky, we may have some simple auto-generated graphs and charts. But 3D rotating visuals of the company’s network with angry red lightning shooting down branches of it to represent a spreading infection… no.The fact is, if we knew how to detect transmission of a virus or other security bsignNow that clearly, we would put all of our effort into PREVENTING that particular security bsignNow rather than making fancy graphics to visualize it. If a security bsignNow does happen, it’s generally because it’s something we weren’t aware could happen and therefore hadn’t taken the right steps to prevent.In addition - and this is a very important point - it is almost always in the best interest of a hacker that their security bsignNow remains undetected. If you send a spy to a foreign agency, do you send them with a big flashing neon sign that reads “You’ve been infiltrated! Bwahahaha!” No, you don’t! That would be stupid!The main purpose of a virus or security bsignNow is to:Steal a company’s customer data (there is a black market for this, and people’s data brings money!)Use a company’s infrastructure to host their own expensive computations (for example, mining bitcoin on their servers)Destroy a company’s data (not as common as there’s not as much profit)All of these tasks are easier to accomplish if the IT staff at the victim company are unaware of the fact that their computers are “infected”. Once they know there’s a problem, they can start doing damage control, and damage control is the last thing hackers want done. Therefore, as you can imagine, viruses and security bsignNowes would generally be designed to be as incognito as possible. So no, a billion windows will generally not pop up on your screen, You will not see any progress bars indicating what % complete the a data theft is. You will not get any skull and crossbones calling card announcing the security bsignNow.*Please note I use the terms “virus” and “hacker” loosely. In reality, a virus is only one specific form of security bsignNow and cannot be used as a blanket term for all security bsignNowes. Also, the term “hacker” actually means a programmer who writes “quick and dirty” programs to accomplish a task quickly but without proper style or maintainability.

Bit coin is a crypto currency and worldwide payment system. It is the first decentralized digital currency, as the system works without a central bank or single administratorWhy Bit coin is more important?Bit coins can be used to buy merchandise anonymously. In addition, international payments are easy and cheap because bit coins are not tied to any country or subject to regulation. Small businesses may like them because there are no credit card fees.

The problem with apps and some browser extensions is the privacy policy. Too many people are not paying attention to them. These software programs are often programmed to communicate with third party data collectors and websites. What are they collecting? A lot of your personal information, activities, web activity like where you shop or do your banking. It's sneaky but the people who develop these programs tell the user in the privacy policy what they are doing. Thus we come full circle; people are not reading the policy and the developers know it. They depend on it! Passwords are often encrypted that's why you see little dots or asterisks when you type them in a website. So the answer is kinda, sorta, no. However if you are using a malicious app or extension or add on it may have key logging feature that records your keystrokes thus avoiding the encryption. Hope this helps.

Both terms - “electronic signature” and “digital signature” - are often used interchangeably, they aren’t exactly the same. Electronic signatures could be considered virtual representations of a pen-and-paper (“wet”) signatures. Digital signatures, also called cryptographic signatures, are a type of electronic signature that’s coded and encrypted in order to prevent the impersonation of a signee, tampering, and improve security overall.The main difference is that a digital signature is mainly used to secure documents and is authorized by certification authorities while an electronic signature (e-signature, e-sign) is usually associated with a contract where the signer has got the intention to do so: Difference Between Digital Signature and Electronic SignatureE-signature helps an individual to show his agreement to the conditions and terms of an electronic service. It can also be used to confirm the identity of the message's creator. Many countries give the same legal importance and significance to e-signatures as to traditional ways of executing documents. Here are the features of some most popular tools in this area: Best E-Signature Software Reviews & Comparisons | 2019 List of Expert's ChoicesWith electronic signature tools you avoid signing digital documents by hand - which is tedious cause otherwise you need to print, sign and scan all that stuff - that’s why such tools are on the rise. If you work with such signatures often, maybe you need some simple free tool which is specialized exactly for your business tasks. It really depends on the purpose for which you need this to sign an already typed document - it is often better to use a specialized tool, like Draw Your Signature Online and Sign PDF - CreateMySignature.com (instead of a regular image editor) to streamline your business documents workflow.

All Roads Lead Back To The Card Issuing Bank To present a cogent insight on this subject, I will need to present an overview how the Interchange system actually works.  This is just a simplistic presentation so as to develop a background on how Apple may be profiting.In a typical traditional merchant account transaction a merchant pays a Discount Rate(s) and Transaction Fee, many merchants, especially the very large merchants have the rates directly tied to the wholesale Interchange Rates [1] published by the payment card companies.  A vast majority, over ~85% of the Discount Rate and Transaction Fee collected actually is paid to the Bank that issued the customer’s credit card.  This means that about ~85% of the component that makes the Discount Rate a merchant will pay, is actually Interchange and is not under the control of the company offering a merchant account.  It is a rate that just about 99.99% of all merchants will pay, it is generally not negotiable.  Hiding The Complexity Companies like PayPal and Square hide all of this complexity and wrap the Discount Rate into a flat fee.  The upside to a small merchant is simplicity, the down side to a large merchant is a rather large cost penalty for this simplicity and it is why most medium and large merchants do not pay flat fees and pay Interchange Plus rates.  Remember the payment card issuing banks will still get the ~85% and thus there has never been a tremendous amount of profit left after processor, brand usage fees and other dues paid directly to the payment card companies are factored.The Apple iWallet Revenue SystemIt is clear that the details of the negotiations Apple held directly with about 20 banks along with direct negotiations with Visa, MasterCard, American Express, Discover, China Union Pay and others will never be open public knowledge.  The best one can do is to use domain experience and form a postulation.  Apple is building a mobile wallet and will use a technology called Host Card Emulation housed in the Secure Enclave of the ARM processor found on the iOS device that will be used for the NFC based transaction.  Under current card company (Interchange) rules these cards are considered “Card Present” transactions.  The Card Present Interchange has always been the lowest cost because in practicality when a payment card is in the hand of a consumer and is swiped through a payment card terminal, the fraud and losses are signNowly lower.  The “Card Not Present” fees are always higher because a stolen payment card is far easier to use when just the numbers are required and thus the Interchange is higher.It was never a debate that Apple’s NFC system would be deemed as Card Present.  The negotiations with top banks and then the payment card companies were produce a consensus with all parties that there is a foundational basis for Apple to earn some portion of the Interchange.  This would amount to a rebate to Apple paid directly from the banks, via the payment card companies for transactions concluded via the iWallet.  One primary reason for the Apple rebate would be based on the fact that the card is more secure in the Secure Enclave, it is in most embodiments, one use tokens with the transmission system via some Verifone terminals afforded end to end encryption. thus could never be a part of any useful hack.Apple will also have a unique way to send a payment card to an App and in do this in such a manner that the transaction may qualify as a Card Present transaction.  This would be accomplished through an API of sorts.  There are a number of very logical use cases for this system and it will be a featured part of the Apple payments model.  This system will not use NFC directly.  Traditionally this would be considered a card not present transaction, however Apple’s extended negotiations may have changed this classification.  There are a few other additional premises on why Apple established a rebate from the Interchange.  One really important consideration to all involved on the other side of the table is the fact that Apple has a tremendous number of payment cards on file, nearly 1 billion.  This could in theory make it very easy for Apple to create a new payment system and challenge all the parities.  Of course Apple does not really want this and certainly the other side of the table would not want this.In the next phases of the iWallet system, Apple will send location data and other identity data to the card issuing banks to assure them that they can crosse reference the exact location of the transaction and the iOS device.   This is a huge anti-fruad feature that no payment card currently offers.So as it stands today Apple is highly likely to have agreements that pass a rebate back to Apple for any iWallet transactions.  There may also be a fixed amount paid to Apple fro every card loaded into the Secure Enclave.The resulting revenues can look like this:Interchange = 1.50% (assumed) Apple Rebate = 0.20% (assumed) A $100 hypothetical iWallet transactionApple iWallet revenue = $100 x 0.20% = 20¢ No Need To Change Merchant Accounts No Costs For iWallet EquipmentTo be very clear, merchants and consumers would not see any cost increases at all.  Merchants do not need to sign up to any particular provider and likely pay $0 for the NFC upgrades since no payment company wants to lose a merchant over a $50 device.  This is in deep contrast to companies like Square, with the now canceled Square Wallet, which required the merchant to sign up to have a Square merchant account to be a part of the closed Square wallet system.   This was a huge flaw in the business premise of the Square Wallet that guaranteed a limited signNow.  Apple wants the widest number of merchants and frankly knows that merchant accounts are not a business they want to be in and will never scale to the adoption level they need.  Additionally, the method Square used, pay with your name, was not considered a “Card Present” transaction by the banks and thus Square absorbed higher fees for this method.  This just about guaranteed the service would lose money no matter how fast or far it scaled.  Apple’s brilliance is in the fact they chose to work with, rather then against, all existing relationships and procedures.   They add signNow value to all participants and are being paid a reasonable amount accordingly.  When the dust settles these negotiations will be recorded in business history as being a masterstroke in the same league of the negotiation Apple had with record labels and cellular companies.You and I will not need to be concerned with all of this detail, the iWallet will just work. ___[1] Interchange fee

Snapchat – falling into line behind Facebook and Twitter – has become the latest social network to report declining user numbers in its half-year results.Snap Inc, the parent company of the app known for its disappearing messages and photograph filters, revealed that in the three months to the end of June active daily user numbers shrank from 191 million to 188 million, a 1.5% decline. It followed a controversial redesign that had prompted more than a million people to sign a petition to reverse the “annoying” changes. It has also faced intense competition from Facebook-owned Instagram.Here are few big things on social media for 2019Increasing Popularity Of Instagram Stories:It is no obscure about the fastest growing social media platform.Instagram is known by each and everyone, especially if one is in the age group of 18 to 35. Yes, it is pretty famous for youth and Instagram has over 700 million users in less 7 years.In a world that is changing on the rapid-speed, images will never end to drive the social media engagement.Videos going to rule social media“Over the next few years, the much bigger driver of the business and determinant of how we do is going to be video, not Messenger,” says Mark Zuckerberg.By 2020, an estimated 80% of global internet traffic will be attributed to videos. Both marketers and consumers are jumping on the videobandwagon: 87% of marketers are using video in their campaigns and 90% of customers say video helps them make buying decisionsShort-Form Video Platform Tik Tok:Formerly known as TikTok - video social network, Tik Tok is self-described as “a destination for short-form mobile videos.”The company’s mission is to make everyone the creator and has built a platform that makes it easy for users to create and share videos with special effects filters, stickers, and more.Content on Tik Tok has an unpolished, authentic look that makes it highly engaging for a younger audience.How marketers can use it:In June of 2018, the platform announced partnerships with several big brands, including Hearst and NBCUniversal, to create original, short-form, vertical-video shows.According to Tik Tok, plans are in place to develop advertising formats and other ways to generate revenue from this original content.IGTV is a Big Thing:IGTV video is an app that can be used alone or in tandem with Instagram.It's essentially Instagram's answer to YouTube in that it's designed for the mobile-optimized viewing of long-form videos.How marketers can use it:While IGTV is still relatively new, it’s likely that viewership will be strong considering Instagram’s current success with video.Instagram Stories see about 400 million daily users, which is twice as many as Snapchat alone.With mobile viewing on the rise, it’s also a strong platform to signNow younger audiences. Today 60% of Instagram’s users are between 16 and 34, evenly split between genders, which gives marketers access to a vast potential audience within the Gen Z and Millennial demographics.Rise of " Video Live"Live video is something that’s been around for a while, especially on YouTube, but its popularity across Facebook and now Instagram has made it a key opportunity for marketers to look out for in 2019.The interactivity of live video makes it a powerful tool for marketers to engage with their audience and strengthen the relationship between a brand and its followers.Messaging Apps Are Going FastIn recent years, messaging platforms have experienced a steady increase of users, outpacing some of the biggest social media channels.Not only are more consumers using messaging services, but they are also increasingly spending more time texting.This year, U.S. adults spent 11 minutes on average using messaging apps, a number projected to grow in 2019.Following a series of scandals surrounding social platforms and changes in the regulatory landscape, many marketers are looking for an alternative marketing channel that’s safe yet engaging and personalized.WhatsApp ads on 2019:Social media marketing agencies and platforms weigh in on Facebook's plan to further monetize its encrypted messaging app.WhatsApp's plans to start selling ad space will give mobile marketers another channel to signNow the 450 million people who use WhatsApp Status, which was launched earlier this year and mimics the popular Stories format originated by Snapchat and copied with great success by Instagram and other platforms.While no one knows what the future holds for social media, platforms are emerging that aim to meet the wants and needs of today’s consumers. As a brand, the decision of which platforms to embrace should be based on which industry trends are most meaningful to your business goals.Free Consultation With Experts
