Security concerns in online marketing.

For both companies and consumers that participate in online business, security concerns are very important. Many consumers are hesitant to buy items over the Internet because they do not trust that their personal information will remain private. Recently, some companies that do business online have been caught giving away or selling information about their customers. Several of these companies have guarantees on their websites, claiming customer information will be private. By selling customer information, these companies are breaking their own, publicized policy. Some companies that buy customer information offer the option for individuals to have their information removed from the database (known as opting out). However, many customers are unaware that their information is being shared and are unable to stop the transfer of their information between companies.

Security concerns are of great importance and online companies have been working hard to create solutions. Encryption is one of the main methods for dealing with privacy and security concerns on the Internet. Encryption is defined as the conversion of data into a form called a cipher. This cipher cannot be easily intercepted unless an individual is authorized by the program or company that completed the encryption. In general, the stronger the cipher, the better protected the data is. However, the stronger the cipher, the more expensive encryption becomes.
