Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention clearer and more obvious, the present invention is further described in detail with reference to specific embodiments below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
People often use private seals to imprint their own name or personality pattern on a private article. But when the item is lost, the pick-up cannot directly contact the owner through the impression.
The invention proposes an inventive idea: when the article is lost, the picker can contact the owner through the impression printed on the article by the specific stamp, and confirm whether the person who takes back the article is the owner before through the impression.
Example one
As shown in fig. 1, the present embodiment provides a lost article retrieval system, which includes a user end.
The user side can be an app integrating a plurality of seal issuer query interfaces. The issuer of the stamp described in this embodiment may be more than one. When each seal issuer produces a seal, different encryption methods may be used to generate a signature print and authenticate a portion for verification on the print, such as different methods for generating public keys and private keys, or different methods for arranging dot matrixes, etc. Therefore, the user side needs to be compatible with the scanning and verification of the seal marks formed by the signature prints of the seals issued by a plurality of seal issuers and the authentication prints, so that the situation that when a picker picks up a lost article, the picker cannot scan the seal marks on the lost article because the existing user side is used, or the user side corresponding to the seal marks is troubled to download is avoided, the enthusiasm of the picker for returning the lost article is damaged, and the picker cannot timely retrieve the lost article is avoided.
The user terminal comprises a first user terminal and a second user terminal.
The first user is the user used by the owner of the article (when the article is lost, the identity of the owner of the article is changed to be lost). The user side has a binding function. The article owner binds the individual seal with the first user side. And respectively uploading the information of the signature stamp and the information of the authentication stamp by an article owner when the article owner binds the first user side, wherein the information of the signature stamp and the information of the authentication stamp are in unique correspondence. In this embodiment, the information of the signature stamp and the authentication stamp both include personal user information, and the first user side may be used to scan the signature stamp and the authentication stamp respectively to upload the information. The owner of the article uploads contact information such as a mobile phone number, a mailbox and the like as registration information, and the contact information can be used as a way for acquiring the contact information of the picker after the article is lost and picked up. The registration information is bound with the user information.
The second user is a user used by a non-owner of the item, such as a picker. When the article is lost (i.e., the article becomes lost) and is picked up by the picker, the picker can scan the impression on the article using the second user end, and the user information is decoded by the verification portion on the impression, in this embodiment, the impression portion corresponding to the public key lattice, so as to determine the owner of the stamp corresponding to the impression.
In particular, when the first user scans the seal impression of the bound seal, the first user may be configured to prompt the user that the seal is bound through the user interface.
The user side also has a contact function. When the second user terminal scans the print on the article, the second user terminal can acquire the contact information of the owner, so that the picker can get contact with the owner, whether the communication connection is carried out with the first user terminal is prompted on a user interface, such as conversation or information sending, or the contact information such as the explicit mobile phone number of the owner is displayed (the contact information of the owner is disclosed in the way, and the information safety is not available), or the contact information of the owner is concealed by the second user terminal, and the contact information is replaced by a forwarding message.
In summary, first, the contact manner of the owner is not limited to the first user end, but also includes a mobile phone number, a mailbox, and the like in the registration information uploaded by the owner when registering the first user end, and the registration information is searched according to the acquired user information.
Second, the way in which the picker contacts the owner may be bi-directional. After the pick-up scans the print, a user interface of the second user end can be set to prompt the pick-up to select to contact the owner actively, or the pick-up can provide personal contact information, the second user end directly sends the contact information of the pick-up to the first user end, or inquires the registration information of the first user end, and sends the contact information of the pick-up to the owner through the contact information of the owner in the registration information, such as sending an email, notifying the owner that the lost article is picked up, and enabling the owner to contact the pick-up.
The system of this embodiment may include a back end. The back end can be used for storing information such as user information, registration information and the like, transmitting information with the user end, such as sending contact information of a picker, uploading user information and the like, and comparing the user information.
When the owner gets contact with the picker and gets back the lost article in the future, the owner carries the seal as a certificate to prove that the owner is the owner of the article. The picker uses the second user terminal to scan the authentication seal on the seal, decodes the user information, compares the user information with the user information obtained by scanning the seal to determine whether the seal and the authentication seal belong to the same seal. I.e. the user side also has an authentication function.
The three functions of the user side are realized on the basis of acquiring user information after the user side performs scanning operation, the functions can be distinguished, and the functions of scanning a signature print and a print thereof and scanning an authentication print are realized by adopting different decoding algorithms respectively.
The system described in this embodiment further includes a stamp. The seal includes a signature seal and an authentication seal. Signature prints are used to imprint the item, leaving a print for the picker to scan, send contact details to the owner, and verify the owner's identity.
In the embodiment, the authentication seal is provided with a private key dot matrix in a seal cutting mode, the private key dot matrix is generated according to a private key, the signature seal is provided with a public key dot matrix in a seal cutting mode, the public key dot matrix is generated according to a public key, the public key and the private key are respectively generated according to user information, and the public key and the private key are uniquely corresponding. In this embodiment, the public key and the private key are generated by adding a random number to the user information. Different seal issuers may use different random numbers as a means of encryption.
When the user obtains the stamp described in this embodiment from the stamp issuer, the user information is provided for the production of the stamp.
Besides the dot matrix for verification, the signature and authentication of the seal are also provided with seal graphics, and a user can design the pattern of the seal graphics by himself, provide the pattern for a seal issuer, and seal the pattern onto an individual seal to serve as a personal identification. The stamp graphics may be provided only on the signature stamp, or may be provided on the signature stamp and the authentication stamp, respectively. When the user stamps an item with a signature, an impression can be left on the item with the personal identification, identifying the item as personal. In this embodiment, the public key lattice is disposed around the seal pattern of the signature seal, and the private key lattice is disposed around the seal pattern of the authentication seal.
In this embodiment, the authentication stamp recess is provided inside the stamp, and cannot stamp an article. The sunken setting of authentication seal can avoid the user to distinguish the sign seal and carry out the trouble of using from, avoids the user to misuse the authentication seal and impress on the article. If only the signature stamp is provided with the stamp pattern, when the user stamps on the article by mistake with the authentication stamp, the personal identification cannot be left on the article, and the user needs to reuse the signature stamp. If the authentication seal is also provided with a seal pattern, when a user mistakenly uses the authentication seal to stamp on an article, although personal identification can be left on the article, the user side needs to be additionally provided with a set of algorithm for scanning and decoding the seal of the private key lattice of the authentication seal, so that the development and use cost of the user side is increased.
The system of this embodiment can decode the owner's user information and registration information in the background system through the reserved print on the article when the lost article is picked up and scanned, so as to quickly determine the lost owner, that is, the system of this embodiment has extremely high accuracy and timeliness to determine the belonging of the lost article.
The system of the embodiment directly sends the contact information of the finder to the owner, so that the owner directly contacts the finder, and the efficiency of finding lost things is improved.
The reservation of the contact information of the owner and the sending of the contact information of the picker are both directly carried out in a background system, a third person does not need to be told, the contact information cannot be snooped by the third person, and the safety of personal information is improved.
When the owner gets back the lost article, the picker can verify the identity of the owner, thereby avoiding cheating and falsifying by other people and improving the correct return rate of the lost article.
Example two
The present embodiment provides a lost article retrieving method, which retrieves a lost article through the system according to the first embodiment, including the following steps.
After obtaining the individual seal, the user binds the seal with the individual user side, i.e. the first user side, or the user uses the same user side to provide user information at the stage of ordering the seal, and the seal is produced according to the user information in the user side, thereby realizing the binding with the user side.
The seal acquired by the user comprises a signature seal and an authentication seal. In this embodiment, the authentication stamp is recessed within the stamp and is used only to verify the identity of the owner and not to stamp an article. The user stamps the item with the signature stamp, leaving an impression. The signature can be designed with a figure of personal identification, and the formed print can be used for visually distinguishing the exclusive property of the article.
After the article is lost, when the picker picks up the article and scans the impression on the article by using the user end of the picker, namely the second user end, the second user end analyzes the user information of the owner in the background system according to the impression, and identifies the owner of the seal corresponding to the impression, namely the owner. And the second user side acquires the contact information of the owner and is used for enabling the pickup to directly contact the owner.
The means of contact may be bi-directional. For example, the second user end prompts the finder to provide personal contact information through a user interface, the contact information of the finder is sent to the first user end through a background system, and the owner initiates contact. Or the second user end searches the mobile phone number of the owner in the background system, hides the mobile phone number and replaces the mobile phone number for dialing, so that the finder communicates with the owner.
After the owner gets in contact with the pickers, the time and place for retrieving the lost article are appointed.
When the lost article is taken back before the lost owner, the lost article is carried with the seal stamped on the article, the picker can scan the authentication stamp of the seal through the second user side, another group of user information is decoded in the background system and is compared and verified with the former user information, and when the authentication is consistent, the identity of the lost owner can be determined, and the lost article is returned.
The user side can be applied to scanning and verification of seals issued by a plurality of seal issuers, the possibility that the user side is used is increased, and the problem that the lost article can not be found out possibly because a picker needs to find the user side corresponding to the seal or needs to download the user side to lose the enthusiasm of returning the lost article is avoided.
