Abstract
Embodiments of a system and method for secure processing of image data are described. Image data included in image files may be encrypted and compressed in a single step using dynamically identified compression/encryption information such as code word tables.
Claims20
A computer-implemented method comprising:
- identifying, by at least one of an optical scanning device, a control server, an image processing server, or a computing device configured to transmit or receive image data, a detail type for an image file, wherein the detail type comprises at least one of an image property or a compression detail;
- obtaining, by the at least one of the optical scanning device, the control server, the image processing server, or the computing device, a count of records corresponding to the detail type;
- determining, by the at least one of the optical scanning device, the control server, the image processing server, or the computing device, that the count of records exceeds a threshold;
- receiving or retrieving, by the at least one of the optical scanning device, the control server, the image processing server, or the computing device, a set of raw image files corresponding to the detail type;
- identifying, by the at least one of the optical scanning device, the control server, the image processing server, or the computing device, current compression and encryption information corresponding to the detail type;
- generating, by the at least one of the optical scanning device, the control server, the image processing server, or the computing device, updated compression and encryption information based at least in part on the current compression and encryption information;
- comparing, by the at least one of the optical scanning device, the control server, the image processing server, or the computing device, compression details for images compressed using the current and updated compression;
- and
- determining, based on the comparing, whether to maintain the current compression and encryption information or replacing the current compression and encryption information with the updated compression and encryption information.

An image processing system comprising:
- a computer-readable memory storing executable instructions;
- and
- at least one of an optical scanning device, a control server, an image processing server, or a computing device configured to transmit or receive image data in communication with the computer-readable memory and configured to execute the executable instructions to at least:
- identify a detail type for an image file, wherein the detail type comprises at least one of an image property or a compression detail;
- obtain a count of records corresponding to the detail type;
- determine that the count of records exceeds a threshold;
- receive or retrieve a set of raw image files corresponding to the detail type;
- identify current compression and encryption information corresponding to the detail type;
- generate updated compression and encryption information based at least in part on the current compression and encryption information;
- compare compression details for images compressed using the current and updated compression;
- and
- determine, based on the comparing, whether to maintain the current compression and encryption information or replace the current compression and encryption information with the updated compression and encryption information.
