  • Patent number: 12294665
    Abstract: A method of labeling video to provide authentication acquires an instruction to apply timestamp labeling. Each recorded video is labeled with a timestamp based on the instruction. The first mark information is generated based on a content of each recorded video as a hash value and is uploaded into a blockchain. Second mark information is generated based on a content of at least one video under investigation. By comparing the first mark information and the second mark information, a video under investigation is found to be undistorted and authentic when the first mark information is the same as the second mark information. The video under investigation is found to be non-authentic when the first mark information is different from the second mark information. A terminal device and a computer readable storage medium applying the method are also disclosed.

  • Publication number: 20250123200
    Abstract: A method for detecting an object containing recycled plastic materials by qualitative and semi-quantitative detections is revealed, in which observing a yellowing condition of the object using a first light source, and illuminating the object using a second light source for observing a defect amount on the surface image of the object. When a yellowing index of the object is smaller than a standard yellowing index as well as a second defect condition is greater than a first defect condition, and an activation energy value of the object from a thermogravimetric analyzer is smaller than a standard activation energy value, the object does contain recycled plastic materials. Since the spectrums of recycled PET and native PET are different, the object contains recycled PET and the proportion of the recycled PET are determined according to the spectrums of fluorescent spectrum analysis and the difference ratio between the spectrums respectively.
