A new product from Voltage Security claims to use a technique that may make implementing database encryption easier. The product, called SecureData, encrypts data without requiring changes to the column lengths.
As anyone who has explored database encryption products will know, implementing a product can be very time intensive requiring lots of effort. A lot of them fail bacause the schema needs to be modified a lot. This is due to the fact that different encryption algorithms produce output of different lengths and column sizes have to be adjusted to accomodate the encrypted values.
If SecureData actually does what it says it does, it may become a lot easier to implement database encryption. In these days of regulations and compliance requirements, this can go a long way in helping secure databases.
