Techniques for cryptographically protecting personally identifiable information in images and videos are described herein. An image may be obtained. One or more regions in the image may be detected based on an object detection algorithm. Pixels for each region of the one or more regions may be encrypted using a symmetric encryption technique and an initialization vector. The encrypted pixels for each region of the one or more regions may be written back into the image. A symmetric key of the symmetric encryption technique and the initialization vector may be encrypted using an asymmetric encryption technique. Metadata of the image may be updated to store the encrypted symmetric key and the encrypted initialization vector.

Cryptographic protection for portions of media

The present invention provides Web Services over a mail transport. In particular, the present invention sends Web Service messages using MAPI (Messaging Application Program Interface) mail applications in order to support offline communications and extended processing time of service requests without creating additional infrastructure for such message exchanges. A custom layer transport is configured to: identify that a Web Service message is to be sent across a mail transport; use the MAPI application to generate a mail message; and include the Web Service message and other identifiers within the mail message. The message is then sent to the outgoing mailbox of the MAPI application for subsequent delivery to an endpoint. Upon receiving the mail message, the endpoint can extract the Web Service message and process it accordingly. Other example embodiments also provide for requesting NPDL (Network Protocol Description Language) data structures (e.g., WSDL documents) by a similar process.
