  • Data storage interface for protocol-agnostic storage services
    Patent number: 11487442
    Abstract: A data storage interface provides access to data storage clusters that may not otherwise be accessible to data accessors. The data storage interface can serve as a point of access for data accessors to access stored data via a consistent data access protocol, even when a data storage cluster on which requested data is stored may use a different protocol. The data storage interface can also provide access across network boundaries, such as those between different private cloud computing systems (e.g., virtual private clouds or “VPCs”).

  • Method for preventing image modification, image capturing device and image verification method
    Patent number: 11418677
    Abstract: A method for preventing image modification, an image capturing device and an image verification method are disclosed. The image modification method includes: processing a compressed image of at least one frame to obtain feature data of the compressed image of the at least one frame; encrypting the feature data to generate a checksum; generating supplemental enhancement information, which at least includes a time parameter and the checksum; and transmitting and/or storing the supplemental enhancement information and the compressed image of the at least one frame together so as to verify authenticity of the compressed image of the at least one frame by using the supplemental enhancement information. The time parameter is a counter value of a counter in the image capturing device and the counter value continuously increases. With the above method, authenticity of image data can be verified.
