  • Publication number: 20230121095
    Abstract: An image capturing apparatus capable of guaranteeing the authenticity of contents while reducing the calculation load of a hash value of an image file. The image capturing apparatus generates an image file, and performs processing for reducing a file size of the image file. A hash value generation section calculates a hash value by applying a hash function to the processed image file. Reduction processing information indicating a method of reducing the file size is generated, and the image file, the hash value, and the reduction processing information are transmitted in a state associated with each other, to a management system that registers data associated with the image file including the hash value in a blockchain.

  • Patent number: 11561703
    Abstract: In an approach to adaptive tape calibration criteria based on the number of dead tracks, the number of rewrite occurrences for each dead track on a tape drive is determined. Responsive to detecting that a head is in a dead track state, the number of dead tracks is stored on the tape drive. A calibration threshold is determined, where the calibration threshold includes the number of dead track rewrites and the calibration reference value for a specific tape drive type. Responsive to the number of rewrite occurrences exceeding the calibration threshold while writing a data set, a calibration of the tape drive.
