Description
Technical field
Information decoding method of the present invention based on circumferential arrangement striped array belongs to packed and transported, encrypting and decrypting and information peace
Full technical field.
Background technology
Net purchase has turned into a kind of consumption pattern indispensable during people live, and express delivery list is also as between both parties
The important documents of transaction.At present, because the personal information of both parties can be directly displayed on express delivery document, and according to express delivery
Information on document is dispensed, therefore the personal information of both parties can be completely exposed in the links of dispatching, this
Just it is easy to cause the loss of personal information.Show according to investigations, the personal information more than 70% is leaked by express delivery document, and this gives
Daily life brings many puzzlements, or even causes serious economic loss.
In face of the safety problem of leakage of personal information, although appealed that government strengthens working out strict prison to logistic industry
Pipe mode, while also improving both parties to the protective awareness of personal information, but because personal information is directly displayed at soon
The mode passed on document does not change, therefore personal information is also just had no idea fundamentally by the problem that express delivery document is revealed
It is resolved.
The content of the invention
Regarding to the issue above, the invention discloses a kind of information decoding method based on circumferential arrangement striped array, the party
Method can change the mode that personal information is directly displayed on express delivery document, and then make what personal information was revealed by express delivery document
Problem is fundamentally resolved.
The object of the present invention is achieved like this：
