In earlier times we had ledger journals which consisted of the records of the various economic transactions or money lending entries. After that we started storing all the information on computers, now the latest thing that has evolved in the market is the Blockchain technology.
Blockchain technology consists of records called blocks, these blocks are connected to one another and are secured using cryptography. It can record transactions between the two parties and in a very efficient and permanent way. The modification in the data of the Blockchain cannot be done once the data is recorded, there is no way to alter the data in it.
Reason behind it being the latest innovative technology
The original use of the Blockchain was to use it in the transaction of the bitcoin currency and now it has spread to various other aspects of the market. In its early development years, the technology faced a lot of disapproval and censorship, but after looking into it deeply and giving it a thought it was decided that it was more secure and productive. It now has taken the place as the technology to store data in a digital way which is update and looked into from time to time. However, this technology blog will tell you all about the benefits of Blockchain and will tell you that how you can enhance your business using it.
Some of the benefits of Blockchain can be described as:
- Authentic: The information that is stored on the Blockchain cannot be given to control by a single person. So there are a very few chances of failure and the business transactions can rely on the technology and be assured of the safety of their data.
- Transparent: Blockchain is a type of distributed ledger. So, all the participants will have the same documentation instead of saving the individual copies. This will create transparency and everyone would be able to view the same data, and the updating or editing on the document can only be done if all the participants agree on it.
- Secure: All the transactions that are to be recorded must be first agreed upon, after approval the current transaction will be linked to the previous transaction. The information is not stored in a single server, rather it is stored on a network of computers which makes it difficult for the hackers and crackers to alter the data.
- Improved traceability: If the company deals in a complex supply product trading, than it could be very difficult to trace the product to its original destination, whereas if the data is stored in a Blockchain it could easily trace the origin of the product because of the interlinking property of the blocks to each other.
- Cost Effective: Cost reduction is the most important part of the business, with Blockchain it gets easier to reduce the middlemen and you can do without them too. You don’t have to trust the trading partner, instead just trust the data on the Blockchain. As everyone will have the access to the single document, so you won’t even have to worry about the reviewing of a lot of documentation.
Adopt These Five Security Measures to Keep Your Apps Secure
Recently there was a huge hue and cry in May when the WannaCry ransomware attacked the worldwide cyber security creating havoc and jeopardizing the function of close to some two and a half million computers in about 150 countries. Its prime target was computers using Microsoft Operating System. Now, the intention of informing you all this is that if you are using an Android or iOS phone, please don’t be under the impression that you are within the ages of a safe umbrella.
Today, when we have the luxury of accessing the internet on our mobile phones, it has become utmost important to guard the devices with the shield of protection. You are already aware of the fact that not all websites are considered safe for visiting. The same can be said about mobile apps as well.
According to the recent survey, it was found that Smartphone owners are using average 30 applications per month. But are you sure that they are 100% hack proof? No, you cannot bet on that. Even a trifling issue can prove to be quite expensive and you have to pay a heavy penalty for it. And beware that nowadays the hackers have become smarter and so you need to be very careful when browsing internet on mobile devices.
In this article you will learn the best five techniques about app security and safeguard your confidential data from getting hacked.
1. Providing Security with Multifactor Authentication
Multifactor Authentication or MFA, in short, is indeed a great in order to combat hacking and cyber crime. The multinational companies offered this facility to their employees but today social media giants such as the Twitter is too offering the same to its users.
Now, you must know how this procedure works? Once you are logging in with your user name and password, you will have to show that you owe a mobile handset too with a different account linked with user account. This is the additional security which will protect your secured information even if the user name or password has been stolen. It will take you less than 10 minutes to set the rules; thereby enabling the multifactor authentication to get activated with the help of Duo Security or Google Authentication. After log in, the MFA will ask to validate with your second device and if you are logging for the first time, then will have to get your device registered with a MFA provider.
Setting the rule is as easy as eating your favorite dish. Once you choose your provider, your next job is to configure the associated rule. One of the biggest advantages of having the rule is that it allows you to configure MFA under various conditions such as geographical location or change of place, type of network or type of device used.
For example, every time you login into your Gmail account from a different device, the Gmail team sends you an email with warning information that your account was logged in from some other device. It also encourages users to keep on changing their passwords at regular intervals.
2. Be Cautious of Malicious Codes
The malignant codes and the mobile malware has certainly become one of the biggest challenges for the cyber security engineers. According to the latest data, approximately about 36.5 million Android devices reportedly infected with malware. Let’s now look into how shrewd these cyber criminals have becoming and how there are choosing their soft target.
The cyber attackers in the first place attain a duplicate copy of the application and then reverse engineer it. Then these most commonly used or popular mobile apps are duplicated or they are launched in the pirated version to be released in the market. These are better known as the ‘Rouge Apps’, which contain the malware codes. They are mostly launched on third party app stores that are not authenticated. These fake or pirated apps are promoted amongst the users, alluring them to install it.
It is important to provide the app developer to beware of such malicious codes and also take note of the loopholes in protecting their apps. As for the users, they should be careful before installing any app into their mobile.
3. Calculation of User Fraud Score
Nowadays, the e-commerce websites have become intensely popular and as such is regarded as one of the frequently visited online marketplaces. However, if you are an owner to one of these marketplaces, such as Quikr, it is your liability to provide a secured and safe environment to all your buyers and site visitors.
The rule book states that you need to calculate a fraud score for every user based on their email id and IP address. This will help you identify whether the user is real or fraud. But how will you do this? The cloud service can be of great help in this regard. What it does is it takes a cumulative data from offline social media authentication as well as web data.
The data will help in securing your app as well as you can also keep a vigil on your users by the high fraud scores. You can ask them to verify their identity before they deal with the other users. Moreover, it is always advisable to keep your user information in your database to avoid hackers entering the site.
4. The Android Keychain and iCloud Keychain
A keychain can be defined as one of the optimal highly protected store house which contains all the confidential information that includes usernames, passwords and other such classified data all at one place. The keychain is developed by the different operating systems providers such as the Android and the iOS. It is much safer to keep all data in keychain instead of p-list and NSUserDefaults. Another plus point of using a keychain is that you don’t have to login every time when you want to open the application.
5. Device Security and Encryption
So till now your focus was on strengthening the security of the mobile application, but did you think over the device? Yes, the device’s security is equally important and it simply cannot be neglected. There is every change of the app coming under the scanner, if it has a jailbroken or rooted device. Therefore, you have to tighten the screws and give the device an unmatched protection from beneath. The app sandbox must be under a strict vigil because rooting or jailbreaking will lead to increase in insecure data and weaken the security model.
Encryption in simple language means to convert any data or confidential information into codes or cipher which is unreadable with the help of some special algorithm keys. It is one of the best-secured ways to protect your data.
Well, although the blog has highlighted the five optimal methods that you can implement to safeguard your data, but the list does not end here. There are various other techniques that can be employed for the data security. You can opt for email verification, keep updating your software, restrict intruders into your phone and so on. Always keep in mind that in order to outdo cyber criminals, you need to be one step ahead of their game plan.
Entering the Magical World of Ethereum
The revolution that cryptocurrencies brought had changed the world in many ways. Bitcoin was the first virtual currency, which gave the influential push to this revolution.
Bitcoin can be described as digital money or virtual money. Bitcoin is one of the oldest cryptocurrencies and it has been flowing around for almost eight years. And, ideally, It is used to send or transfer money from one party to another party.
But, that was years ago, and along with Bitcoin, there are other popular cryptocurrencies also subsist in the market.
According to some cryptocurrency survey websites, there are more than 1,658 cryptocurrencies available and running currently on the internet. Just a few of these currencies are legit and successful today.
We can’t argue about the prominent position that Bitcoin holds, but there were some problems associated with it, like- not having any rule or condition to send the digital money. The scripting language on which the bitcoin was written is not flexible and it cannot be modified further (only possible if the developer is involved). This leads to limited functionality and operations, which cannot be extended to add multiple features to it.
Ethereum, the another cryptocurrency, is now blooming on the internet. And, even, it also surprised the entire world, just after its launch. It is not just a Cryptocurrency development company like Bitcoin. But, it is a complete infrastructure built on blockchain, which offers its users to build and run decentralized applications.
What makes Ethereum different from the well-known digital currency, Bitcoin?
Ethereum uses the Ghost Protocol, which sets up the block time to 15 seconds, while in Bitcoin, it is set to 10 minutes.
The specialty of Ethereum is that it uses Smart contracts in between the transactions to smoothify the exchange by using conditions and rules for every specific token used. For example, if Sender A wants to send money to Sender B, but this transaction must expire before given date. It is possible by programming the smart contracts to execute, only when certain conditions are met.
Ethereum is flexible in providing its developers the power to create decentralized applications with multiple operations. Decentralized applications can do miracles by eliminating the intermediaries or any third party in between the operations. Unlike traditional applications, which run on centralized systems, decentralized applications cut out the possibility of failures and errors on any single point.
Basically, Ethereum uses wallets, which provide the interface to users to manage their tokens and smart contracts. For example, Erc20 has compatible wallets, which can be developed by a reputed Erc20 development company.
Despite of all facts and figures, the possibilities of Ethereum are endless. But, here are some of the main advantages, which make it way apart from other cryptocurrencies:
- Ethereum has its own language on the blockchain, which is called the Turing. This grants the ability to exchange complicated contracts on the network and it removes third parties too.
- It is corruption-free because any kind of censorship is not possible.
- The DApps created and connected to Ethereum never go down or get shut down.
- Ethereum can be used as donations for other projects.
- It doesn’t have any limit on megabytes.
- Ethereum is faster than Bitcoin because of the less block time.
Do you observe?
How amazing the Ethereum is!
There is a very bright future for this blockchain platform, where it will definitely prove as a boon for large organizations, companies, and government agencies as well.
