Abstract: A user interface and interactive application for redacting digital documents are disclosed. This technology allows an operator to perform document recognition and redaction on a small number of representative files and receive feedback on the accuracy of these processes before committing to potentially long and processor-intensive redaction of a larger collection of files. This methodology saves both processor time and operator time for redacting documents, and achieves accurate redaction of a complete set of documents more rapidly than with other commonly-used methods.

Abstract: A system for making encryption and decryption available to software applications as a service is disclosed. An encryption/decryption server verifies the credentials of human operators, hardware devices, or combinations of operators and hardware devices and determines the cryptographic keys to which they have access, and provides access to said keys. Client software applications send service requests to the encryption/decryption server to encrypt or decrypt data. The server encrypts or decrypts the data as requested if the operator or device has the proper credentials to access the required key. The system may include multiple levels of security access.
