Embodiment Construction

[0045] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0046] figure 1 It is the quantum flow data block storage and management process of the preferred embodiment of the present invention. In the first step S01, the continuous streaming media file is first sliced ​​into quantum data slices by the streaming media processing system 406 ; The second step S02 is to slice a group of quantum flows (Herein referred to as the quantum flow data block) corresponding sequence j is encrypted into r by DES, here, the encryption key is , the quantum flow data is ; The third step S03, will add j encrypted quantum data Packed into quantum flow data blocks ; The fourth step, the qua...

Abstract

The invention discloses a streaming media quantum stream data block structure and an encryption and decryption method. The method comprises the following steps: first step, slicing continuous streaming data into quantum data slices (the formula is described in the specification), wherein a content mark i and a sequence mark j are provided; second step, encrypting j as r by using a data encryptionalgorithm; third step, merging (the formula is described in the specification) quantum streams corresponding to a group of r into a quantum stream data block; and fourth step, storing the quantum stream data block in a randomly allocated cloud storage device and a backup device, wherein encryption algorithms and keys thereof and storage and backup addresses of the quantum stream data block are stored in a quantum stream management database. When a user wants to download reading contents, an index file is obtained from the management database, the quantum stream data block is downloaded according to the data storage address, the sequence mark j corresponding to the r is decrypted by using the encryption algorithms and the keys, the (the formula is described in the specification) is restored, and a data file is reorganized and restored in sequence.

Description

technical field [0001] The invention relates to the fields of streaming media data quantization processing and cloud storage, in particular to a streaming media quantum stream data block structure and encryption and decryption processing. Background technique [0002] With the widespread popularity of Internet applications, the storage and access of massive data has become a bottleneck in system design. Segmenting data can reduce the load of a single machine. Through the load balancing strategy, the access load of a single machine is effectively reduced, and the possibility of downtime is reduced; through the cluster solution, virtual storage and backup, data security is increased. and reliability; through multi-channel reading and writing, the speed and concurrency of reading (Read) data in the application can be greatly improved. [0003] Data segmentation is not a new technology, but a relatively simple software concept. For example, a multimedia streaming file is a lar...
