Abstract
The method of confirming e-mail text and appendix is for the e-mail server to treat each received e-mail mathematically to obtain one corresponding character string mark and to save the character string mark in one third party memory device other than the emitter and the receiver. In case that either the emitter or the receiver juggle the e-mail text and appendix, the third party can provide the intact e-mail text and appendix with the stored character string mark. The present invention makes it possible for the e-mail to be used as the effective evidence simply and practically.
Description
One, technical field
The present invention relates to a kind of method that can confirm e-mail text and annex.
Two, background technology
Email is one of most popular several application on the internet, it has been deep among people's work and the life, yet, because e-mail text and annex are easy to be distorted, so it does not possess the letter as traditional handwriting, the contract text of counter signed, the function that can serve as vaild evidence.Although some method can confirm in theory as digital signature whether e-mail text and annex were distorted at present,, be difficult to be accepted by masses owing to using inconvenience, being difficult for understanding and not having reasons such as the third party witnesses.
Three, summary of the invention
1, goal of the invention: the purpose of this invention is to provide and a kind ofly can confirm whether e-mail text and annex were distorted and the method for easy operating.
2, technical scheme: the method that can confirm e-mail text and annex of the present invention is characterized in that this method may further comprise the steps:
(1) e-mail server is whenever received and after the envelope mail e-mail text and the annex of being received is carried out mathematics manipulation, obtains a corresponding characters string sign with it;
(2) e-mail server is stored in this character string identification on the third-party memory device except that the transceiver people;
When (3) needing, Email User can re-send to the third party of above-mentioned store character string sign with its Email of having received or having sent;
(4) third party carries out and the duplicate mathematics manipulation of above-mentioned e-mail server after receiving this Email, generates a new character string identification;
(5) third party judges whether to exist and the duplicate character string identification of newly-generated character string identification from the character string identification of being stored, if having, illustrates that then Email was not distorted.
Above-mentioned mathematical processing methods can be utilized the MD5 hash algorithm (hashing algorithm) that is widely used now, also can utilize the close algorithm of other functions.
3, beneficial effect: confirm with the corresponding character string identification of Email whether e-mail text and annex were distorted because of what utilization of the present invention was stored, so that Email possesses the function that can serve as vaild evidence to a certain extent, and this method is simple and feasible, can be widely used.Electronic mail service system disposal route of the present invention has following function and characteristics: can be produced evidence by the third party, prove whether e-mail text and annex were distorted, so increased substantially the validity that Email serves as evidence; The third party only stores Email is carried out resulting character string identification after the mathematics manipulation, rather than storage of e-mails itself, so can not increase the risk that Email content is revealed; Except that email server software, the software that transceiver people uses, and transceiver people's using method and custom do not need to make any modification.
Four, embodiment
The method that can confirm e-mail text and annex of the present invention is cooperated by following two steps and to finish, and is described in detail as follows:
Step 1: the existing email server is increased following processing:
1, e-mail server is whenever received and after the envelope mail e-mail text and the annex of being received is carried out mathematics manipulation, obtains a corresponding characters string sign with it;
2, e-mail server is stored in this character string identification on the third-party memory device except that the transceiver people;
Above-mentioned mathematical processing methods can be utilized the MD5 hash algorithm (hashing algorithm) that is widely used now, also can utilize the close algorithm of other functions.
Step 2: e-mail text and annex are confirmed by the third party:
Suppose that user A receives that user B sends to his an envelope Email, afterwards for a certain reason, user A distorts Email or the user B that this envelope received and distorts the Email that this envelope has sent.
1, Email User A or B re-send to the third party of above-mentioned store character string sign with its Email of having received or having sent;
2, after the third party receives this Email, carry out and the duplicate mathematics manipulation of above-mentioned e-mail server, generate a new character string identification;
3, the third party judges whether to exist and the duplicate character string identification of newly-generated character string identification from the character string identification of being stored, if having, illustrates that then Email was not distorted;
4, in the time of necessary, third party unit can also submit to the paper document that covered official seal to give Email User A or B, as vaild evidence.
Claims (2)
1, a kind of method that can confirm e-mail text and annex is characterized in that this method may further comprise the steps:
(1) e-mail server is whenever received and after the envelope mail e-mail text and the annex of being received is carried out mathematics manipulation, obtains a corresponding characters string sign with it;
(2) e-mail server is stored in this character string identification on the third-party memory device except that the transceiver people;
When (3) needing, Email User can re-send to the third party of above-mentioned store character string sign with its Email of having received or having sent;
(4) third party carries out and the duplicate mathematics manipulation of above-mentioned e-mail server after receiving this Email, generates a new character string identification;
(5) third party judges whether to exist and the duplicate character string identification of newly-generated character string identification from the character string identification of being stored, if having, illustrates that then Email was not distorted.
2, the method that can confirm e-mail text and annex according to claim 1, it is characterized in that e-mail server carries out mathematics manipulation to every envelope Email of being received, generate a corresponding characters string sign with it, later available it confirm whether Email was distorted.
