Abstract
The invention discloses a kind of data security method, including：Obtain data save from damage save from damage in request a little enter to join information, it is described to enter to join information and include chain code and flow instance mark；According to the operation flow template of acquisition, enter described in checking and join information, and received after being verified and save point data from damage；When last for saving a little non-operation flow template from damage is saved from damage, the next chain code saved from damage a little and the flow instance mark of generation are returned.The present invention solves data in the prior art and saves information from damage and can not carry out validation verification, saves the problem of logical miss easily occurs for data from damage.
Description
Technical field
The present invention relates to the methods, devices and systems that a kind of data are saved from damage.
Background technology
As computer internet is throughout application, electronic data is used as using computer as carrier, is entered using electronic form
Row obtains, fixed evidence form, not only has very high efficiency, and ensure that the safety of original document.Electronic data is not allowed
Easily distorted by people, and there is the legal effect equal with papery evidence.It is with spreadsheet format (text that electronic data, which is saved from damage,
Word, figure, letter, numeral, three-dimensional symbol, color combination and sound and above-mentioned factor combination etc.) existing for all kinds of electron numbers
It is believed that breath, carries out computing, encryption fixation, states clearly and save generation standard time, operation values, Docket No. etc. from damage, prevent from being distorted by people,
Ensure the program and method of electronic data primitiveness and objectivity.Saved from damage by data and the anti-of electronic data content is effectively ensured usurps
Change, ensure convenience and security that data are saved from damage.But electronic data carry out data save from damage when, it is necessary to ensure to save data from damage
Save order from damage, confusion does not occur for the logic for saving data from damage, also to prevent that malice is mixed into electronic data palms off data.
How to ensure that data are saved from damage in sequence, save from damage and do not occur to repeat to preserve in data, prevent from palming off data to saving from damage
The pollution of data, turn into electronic data urgent problem to be solved when carrying out data and saving from damage.
The content of the invention
In view of technological deficiency present in prior art and technology drawback, the embodiment of the present invention provide overcome above mentioned problem or
The methods, devices and systems that a kind of data that person solves the above problems at least in part are saved from damage.
