The approach taken with this product is to intercept the database calls and watch for credit cards being stored or retrieved. If a CC is being stored it’s encrypted and if it’s being retrieved it’s decrypted. This process is only executed for programs running in the Ecometry environment. In order for a program to successfully retrieve the credit card number it must be run using the correct XL’s in the correct order.

Key Management

By default the Encryption key is not stored anywhere. The key is calculated using a proprietary algorithm and every credit card stored is stored with a different key. This makes administration easy and very secure. Should you wish to set your own encryption key you can do so by using the key manager program. The encryption key stored in a binary form in the code base.
