| 20110314300 | Segmented Mapping - Described are methods and apparatus, including computer program products for masking data. The inventions involves receiving a mapping scheme with a number of segments and a different cryptographic algorithm for each segment and then receiving a target value to be masked. The target value is then split into a number of segments based on the number of segments of the mapping scheme and the cryptographic algorithm is applied for each segment in the mapping scheme to each segment of the target value to generate an encrypted segment for each segment in the target value. Then, the encrypted segments are concatenated to create a masked value. | 12-22-2011 |
