Secure Delivery Method for Preserving Data Integrity of a Video Frame with Sensitive Objects
Source abstract
Abstract
Data integrity and authenticity verification are essential requirements to provide reliability for applications running in a video delivery system. We design a prototype system for handling data integrity as well as encoding sensitive objects in a video frame. This system is composed of two components, a logger and a verifier. The logger operates a cryptography hash function of a feature vector of a video data frame and an XOR encoding scheme used for hiding the privacy information of sensitive objects in the video data frame. The XOR encoding scheme is operated at the encoder as part of the logger. The hash value outputted from the hash function is signed by a private key owned by the logger. It is listed as one of the attributes in the metadata of the video frame. In the key distribution phase for the authenticity verification process, the logger maintains the private key, and the public key is stored on the verifier by handshaking. In order to reduce the processing load for data integrity verification, a hash tree configured for each stream of sensor data is used to minimize the verification time. This paper is mainly focused on the design of a logger for data integrity verification and encoding of sensitive objects. To evaluate performance of the proposed method, we build a prototype in a client–server manner. The designed method is operated on the logger, used to mitigate the risk of video data frame tampering and to significantly help in preserving sensitive objects securely.
