As shown in figure 5, the first embodiment triggers verification for describing, in conjunction with based on the access request for cache contents
This mode come the method that is verified, and include following example step：
The abstract of source resource A is written to block chain for source station；
The API for refreshing the cache resources A in cloud distribution network node is called in source station, is written to cloud distribution network node
The copy of newest resource A is as cache resources A；
Client sends the HTTP request to cache resources A to cloud distribution network node；
Cloud distribution network node generates the abstract of cache resources A；
Cloud distribution network node reads the abstract of source resource A from block chain；
Cloud distribution network node verifies the consistency of two abstracts.
That is, in this first embodiment, being triggered by client request：
1) when client request accesses to the resource, the resource that cloud distribution network node caches oneself uses
Algorithm same with source station calculates digest value (that is, abstract of resource A)；
2) cloud distribution network node connects block chain network, searches digest value that the resource is submitted by source station (that is, source resource
The abstract of A)；
3) comparison step 1) and digest value 2), if it is not the same, then illustrating that the content of cache server is tampered, with source
Publication content of standing is not inconsistent.
Fig. 6 schematically illustrates the second embodiment of cloud distribution network cache contents method of calibration according to the present invention.

In conjunction with the above method according to the present invention, it is also proposed that a kind of computing device, including memory, processor and storage
On a memory and the computer program that can run on a processor, the step of processor realizes the above method when executing program.
Above-mentioned technical proposal according to the present invention is stored the summary data of source station content using block chain, utilizes block
The data stored in chain network can not tamper (that is, Information Security), realize a kind of safer source station content and pluck
Storage method is wanted, accurate school can be made to the consistency between source station content and cloud distribution network cache contents to ensure that
It tests.
Above-mentioned technical proposal according to the present invention, has the characteristics that：
1. using in block chain network data can not tamper, the abstract of Internet resources is stored by block chain.
2. what is stored on block chain is abstract rather than the full content of resource, space hold smaller is mainly considered.
And the integrality of resource has been judged enough using summary info, this is ensured by specific digest algorithm.
3. block chain network can jointly be built by cloud distribution network manufacturer and source station, for example, can be in cloud distribution network
Block chain client is run on node.The cloud distribution network manufacturer that this block chain network is added can have more families, such case one
As be likely to occur in source station client and meanwhile using Liao Duojiayun distribution networks manufacturer service when.
4. source station is as uniquely having permission the side being written, it is ensured that the legitimacy of data.
5. source station carrys out the abstract of storage resource without separately building the database of centralization.
6. for security consideration, the abstract of cloud distribution network node not storage resource.
7. this scheme is the solution of decentralization.
8. cloud distribution network node can participate in the composition of block chain network, can not also participate in.
9. cloud distribution network node is directly based upon the initial data in block chain to resource integrity verification, and this is original
Data ensure its legitimacy and integrality (will not be maliciously tampered or counterfeit) by block chain network.
10. any block chain node can be voluntarily added to form the diversity of block chain network node, further in source station
The participant of dispersed nodes improves reliability.
The These characteristics of above-mentioned technical proposal based on the present invention, above-mentioned technical proposal of the invention have the following advantages：
1. utilizing block chain, the risk that data are tampered after single, centralization database is attacked is reduced.
2. successfully source station user and cloud distribution network service provider are combined together by block link, by what is detached in the past
" resource holder " and " caching resource side " closely combine, and realize the guarantee of data consistency.
3. the block chain used in above-mentioned technical proposal according to the present invention can be the block chain network of full disclosure, because
This, can make full use of the computing resource of external (non-source station or cloud distribution network service provider) to ensure the complete of resource data
