Technology Encryption and Beyond

Encryption is an important part of protecting your information from being hacked or stolen. Companies employ encryption services to protect the information they collect from customers and affiliates. The encryption services make it safer to submit payment information online and to send private email to other people. As hackers have become better at retrieving private information, the encryption software has also improved. Barcodes, QR codes, and encryption tools work together to make tracking and storing information easier.

Barcodes

Barcodes were first invented to make storing and stocking items in a store much easier. The scanner could indicate when one unit of a product was purchased and allowed stores to easily see when they needed to order more. If you are trying to market and sell a product you will need to create a barcode for it, so that stores will be able to stock it. Many people can figure out the information on the barcode themselves, or with minimal research on a computer. Barcodes revolutionized the stocking and ordering system for stores. However, because barcodes are simple lines in a set space, it has become easier to hack the information and change it or create fake barcodes.

QR Codes

QR codes are a more complex version of the traditional barcode. They use squares of dark and white space to encrypt the information that is stored. More companies are moving towards using QR codes because they allow more information to be stored. Some colleges, museums and libraries are using QR codes to store information for patrons. The patrons can scan the QR codes with an application on their phone and be connected to specific information about a painting they were looking at or a book they were searching for. Additionally, the United States Department of Energy has begun to use QR codes so that consumers can research product specifications while shopping.

Encryption Software

Encryption helps to protect information that is passed electronically. Encryption software will put the information into code so that it can be transmitted over the Internet safely. When it reaches its destination the same software will decode it for the user. As companies use the Internet to access personal information it puts them at risk for hacking. Barcodes and QR codes make storing and accessing information easier. A good computer system for a company will have excellent encryption abilities to protect the consumer and the business. Personal computers should also have encryption software installed to protect your personal information.
