Abstract
Official abstract text for this publication.
Embodiments include a computer system, method and program product for encrypted file access. An access program module, connected to at least one file system, intercepts a data request for accessing a plaintext file with information stored physically and consecutively on a hard disk and having a pre-determined order and length expected by a program that sends the data request, wherein the plaintext file includes a plaintext record having a key field and a plaintext data field. The access program module determines an encrypted file, associated with the plaintext file, based on a configuration file and the data request, wherein the configuration file indicates the encrypted file associated with the plaintext file. The access program module determines one or more encryption keys based on the configuration file. The access program module accesses an encrypted data field within the encrypted file based on the encryption keys and the key field.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer program product for encrypted file access comprising: a computer readable storage medium and program instructions stored on the computer readable storage medium, wherein the computer readable storage medium is not a transitory signal per se, the program instructions comprising: program instructions, for an access program module connected to at least one file system, to intercept a data request for accessing a plaintext file with information store…
