Sensitive data aliasing
Database management and security is implemented in a variety of embodiments. In one such embodiment, data sets containing sensitive data elements are analyzed using aliases representing sensitive data elements. In another embodiment, the sensitive data elements are stored in an encrypted form for use from a secure access, while the alias is available for standard access.
1. An apparatus for encoding data sets containing sensitive information and generating aliases to represent data elements, the apparatus comprising:
a storage device configured to store and provide access to sensitive personal data sets; and
at least one computer processor configured to
apply an encryption method to encrypt certain data elements in the sensitive personal data sets to produce encrypted data elements in order to disguise or hide user-identification information,
generate aliases that are independent from the encrypted data elements,
generate an association between the aliases and the encrypted data elements, and
provide at least two levels of restricted access to the encrypted data elements via an interface, including a first level through which a set of standard users retrieve information from or associated with the sensitive personal data sets but without the user-identification information, and including a second level through which another set of authorized users retrieve information from or associated with the sensitive personal data sets and with access to the user-identification information even though the user-identification information is disguised or hidden by way of the encryption method.
2. The apparatus of claim 1 , wherein the computer processor is further configured to provide the set of standard users the aliases in place of the encrypted data elements to disguise or hide the user-identification information in the first level of the restricted access.
3. The apparatus of claim 1 , wherein the computer processor is further configured to decrypt the encrypted data elements as part of providing the other set of authorized users with access to the encrypted data elements in the second level of the restricted access.
4. The apparatus of claim 2 , wherein the computer processor is further configured to decrypt the encrypted data elements as part of providing the other set of authorized users with access to the encrypted data elements in the second level of the restricted access.
5. The apparatus of claim 1 , the computer processor is further configured to track and create a log of activities, including access communications, by at least one of the set of standard users and the other set of authorized users.
6. The apparatus of claim 1 , the computer processor is further configured to track and create a log of activities, including access communications, by each of the set of standard users and the other set of authorized users.
7. The apparatus of claim 1 , wherein the sensitive personal data sets include credit card information.
8. The apparatus of claim 1 , wherein the sensitive personal data sets include medical information.
9. The apparatus of claim 1 , wherein the sensitive personal data sets include social security information.
