Ad data cochain is the process that ad content is added in credible alliance's chain by advertiser in the present invention.It is credible Alliance's chain is by multi-level encryption, common recognition mechanism by data cochain, and ad data can not be revoked once cochain, distort, advertisement number According to the full disclosure, transparent, traceable in credible alliance's chain, solves the letter between advertiser, media companies and consumer Appoint problem, as shown in figure 4, steps are as follows:
Step 401, advertiser provides ad data, and ad data may be text, picture, video or their group It closes.
Step 402, Hash calculating is carried out to advertising information, be calculated hash value H (W), and obtained Bit String is turned Turn to integer e.
Step 403, using the public key cryptography of digital signature, the Hash functional value h of advertising data information is counted Word signature, it is assumed here that the elliptic curve parameter used is D=(p, a, b, G, n, h), and corresponding key pair is (k, Q), wherein Q For public key, k is private key, is digitally signed as follows:
1. generating random number d, 1≤d≤n-1；
2. calculating dG=(x1, y1), integer is converted by x1
3. calculatingIf r=0, random number is recalculated, d is otherwise calculated-1mod n；
4. calculating s=d-1(e+kr)mod n；
Then (r, s) is the signature of advertising information.
Step 404, block file manager safeguards the currentFileWriter of a presently written block file, writes The data for entering block file include two parts, and one is block size, the other is block data.In the block file of write area Block size and block data are handled by serializing.After if block size and serializing were written, current block text The size of part is more than setting value, then can be written in next block file.A new block checkpoint information is created, is saved Into database.
The data information after analysis is fed back to advertiser by media companies in the present invention, i.e., logical in instantiated chain code On road, a transaction is initiated, this transaction content is user behavior data and big data analysis result.It is instantiated On chain code channel, from a calling transaction is initiated to the overall process finally kept accounts as shown in figure 5, steps are as follows:
