Device and method to render multimedia data stream tamper-proof based on block chain recording

#The subject matter herein generally relates to verification by block chain.

#Block chain technology provides distributed data storage, point-to-point transmission, a consensus mechanism, and encryption algorithms. The block chain technology employs a consensus mechanism such as Proof of Work to achieve validation of a block in a chain. A mathematical algorithm can establish rights between different nodes in the block chain system.

#Surveillance devices or audio recording devices are common in a specific area, and recorded content can be used as an evidence in court when necessary. However, content said to have been recorded is easy to forge and proving a recording time of recorded content is not automatic.

#Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.

#FIG. 1 illustrates a block view of an embodiment of a block chain system according to the present disclosure.

#FIG. 2 illustrates a block view of an embodiment of a device for preventing tampering with multimedia data stream based on the block chain system of FIG. 1.

#It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one”.

#Several definitions that apply throughout this disclosure will now be presented.

#The connection can be such that the objects are permanently connected or releasably connected. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series, and the like.
