Description
Technical field
The present invention is based on the information decoding methods of circumferential arrangement striped array to belong to packed and transported, encrypting and decrypting and information peace
Full technical field.
Background technique
Online shopping has become a kind of consumption pattern indispensable in for people's lives, and express delivery list also becomes between both parties
The important documents of transaction.Currently, since 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
It is just easy to cause the loss of personal information.It shows according to investigations, the personal information more than 70% is leaked by express delivery document, 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 having appealed that government reinforces working out logistic industry in stringent prison
Pipe mode, while also both parties are being improved to the protective awareness of personal information, but since personal information is directly displayed at fastly
The problem of mode passed on document does not change, therefore personal information is revealed by express delivery document is also just had no idea fundamentally
It is resolved.
Summary of the invention
In view of the above-mentioned problems, 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 reveal personal information by express delivery document
Problem is fundamentally resolved.
The object of the present invention is achieved like this:
Based on scratch layers outside the information coding structure of circumferential arrangement striped array, including coding internal layer and ink, the ink
