[0002] In order to better balance the freedom and control of data flow and strengthen the data subject's control over their personal data, the "right to data portability" has been proposed as a legal right of the data subject. The right to data portability means that when the data controller processes the user data in an automated manner based on the data subject's consent or based on a contractual agreement, the data subject has the right to obtain a copy of the aforementioned data related to him or her that he or she has provided to the data controller; at the same time, the data subject has the right to transmit such data copies to another data controller.

[0063] In order to make the objects, features and advantages of the present application more obvious and understandable, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0064] The inventors analyzed the prior art and found that the specific problems that could not be effectively implemented due to technical and trust issues include:

[0065] 1. Identity verification of data recipients and senders requires the introduction of external systems, such as a credible third party.

[0066] 2. It is difficult to ensure uniformity in the data formats and metadata processed by different personal information processors. Personal information processors cannot guarantee to provide data export / import interfaces that are compatible with the systems of other personal information processors. Currently, there is no authoritative platform for unified metadata and data formats.

[0067] 3. After the data copy is generated and transmitted by the user himself, there is a risk of tampering, and it may also be forged, and may lose credibility and cannot be accepted by the data recipient. If a digital signature is used for the data copy, there will be a CA trust issue, and using a certificate issued by an authoritative CA will introduce additional expenses for special certificate application and maintenance.

[0068] 4. If a data controller directly transfers personal information related to a data subject to another data controller, both parties must prove that the transfer has been approved by the data subject. This may require the introduction of negotiation or association operations, making the process complicated.

[0069] These factors will affect the transfer and circulation of personal information.

[0070] Example 1

[0071] Reference Figure 1 , showing a method for implementing data portability based on blockchain technology provided by an embodiment of the present application, the method involving an alliance chain, a data subject, a data sender, and a data receiver;

[0072] include:

[0073] S110. When the data recipient receives the transaction information sent by the data subject, the data recipient initiates a data matching request to the alliance chain; wherein the alliance chain is further used to accept the data matching request from the data recipient, and send the transaction information matching the data matching request to the data recipient;

[0074] S120, the data recipient receives the transaction information corresponding to the data subject matched from the alliance chain;

[0075] S130. When the transaction information sent by the data subject is consistent with the transaction information matched from the alliance chain, the data recipient stores the transaction information in the local system of the data recipient.

[0076] In the embodiments of the present application,

[0077] Below, a method for implementing data portability rights based on blockchain technology in this exemplary embodiment will be further explained.

[0078] It should be noted that the alliance chain described in the present invention is a personal information transfer alliance chain created by an institution or industry association, and each legally operating institution voluntarily joins the alliance chain after real-name authentication. The data subject refers to the owner of the data, that is, the individual, organization or entity that owns or controls the data. The data sender and the data receiver are both data controllers. The data subject receives the personal data about itself provided to the controller (ie, the data sender) in a structured, common and machine-readable format, and has the right to transmit the data to another controller (ie, the data sender and receiver) without hindrance.

[0079] As an example, see Figure 2-5, the data sender (i.e., institution A) and the data receiver (i.e., institution B) have both joined the alliance chain through real-name authentication. After the data subject makes a transaction request for data transfer to the data sender, the data sender verifies the personal identity of the data subject. When the identity verification is passed, the data sender responds to the request of the data subject and provides the transaction information of the data subject in electronic form. The transaction information is a copy of personal information, which can be encrypted or unencrypted. At the same time, the data sender publishes a transaction on the alliance chain, and the content of the transaction information is the hash value of the copy file or content of the personal information. The alliance chain receives the transaction information sent by the data sender.

[0080] The data subject will download a copy of the above personal information from the data sender and can view the contents of the copy but cannot modify it.

[0081] As another example, if the data subject fails to pass the identity authentication of the data sender, the data sender rejects the transaction request of the data subject for data transfer.

[0082] In a specific implementation, after the data subject passes the identity authentication of the data sender, the data sender publishes the hash value of the copy of the personal information of the data subject to the alliance chain. This embodiment uses the anti-tampering characteristics of the blockchain to solve the problem of authenticity verification of the copy data, and adopts the method of separating the file and the hash value, and only saves the hash value of the personal data copy file on the blockchain. Since the hash value is a process of mapping data of any length to a fixed-length hash value, it has a streamlined feature to avoid the problem of the alliance chain becoming large and bloated due to the large size of the personal information copy file. Subsequently, by calculating whether the hash value of the file is on the chain, it can be determined whether the file has been officially released and whether it has been tampered with.

[0083] In an embodiment of the present invention, before step S110, the method further includes:

[0084] S100, the data recipient verifies the identity of the data subject;

[0085] S101. When the identity authentication of the data subject is passed, the data recipient waits for the data subject to upload the transaction information.

[0086] As an example, see Figure 3-4 The data recipient opens a personal information import interface, accepts the data subject's data transfer transaction request, and verifies the data subject's identity information. When the data subject's identity authentication is passed, the data recipient waits for the data subject to upload a copy of the personal information.

[0087] As another example, if the data subject fails to pass the identity authentication of the data recipient, the data recipient rejects the data subject's request to import personal information.

[0088] As described in step S110, when the data recipient receives the transaction information sent by the data subject, the data recipient initiates a data matching request to the alliance chain; wherein the alliance chain is also used to accept the data matching request of the data recipient, and send the transaction information matching the data matching request to the data recipient.

[0089] In an embodiment of the present invention, the specific process of "the data recipient receives the transaction information sent by the data subject" in step S110 can be further explained in combination with the following description.

[0090] As described in the following steps, the data receiver calculates a hash value of the transaction information sent by the data subject.

[0091] As an example, see Figure 2-5 After the data subject passes the identity verification of the data recipient, he / she shall submit a copy of his / her personal information to the data recipient in the manner provided by the data recipient. The copy of personal information shall be confirmed and submitted in person by the data subject user to ensure that the transfer of personal information has been informed and agreed by the user.

[0092] After receiving the copy of the personal information of the data subject, the data receiver calculates the hash value of the copy file. The data receiver initiates a data matching request to the alliance chain, and after receiving the request, the alliance chain queries the transaction information matching the data matching request and returns the query result to the data receiver.

[0093] As described in step S120, the data recipient receives the transaction information corresponding to the data subject matched from the alliance chain.

[0094] It should be noted that in addition to recording the hash value of the copy of personal information, the alliance chain may also record other data, such as personal subject identity identification, etc., which is defined by the alliance chain organizer and is not limited by the present invention.

[0095] As an example, after the data recipient queries the transaction information from the alliance chain, it obtains the hash value of the copy of the transaction on the alliance chain.

[0096] As described in step S130, when the transaction information sent by the data subject is consistent with the transaction information matched from the alliance chain, the data recipient stores the transaction information in the local system of the data recipient.

[0097] In one embodiment of the present invention, the specific process of step S130 "when the transaction information sent by the data subject is consistent with the transaction information matched from the alliance chain, the data recipient stores the transaction information into the local system of the data recipient" can be further explained in combination with the following description.

[0098] As described in the following steps, the data recipient verifies the identity of the data subject based on the transaction information on the alliance chain;

[0099] As described in the following steps, when the identity authentication of the data subject is passed, the data recipient compares the hash value of the transaction information sent by the data subject with the hash value of the transaction information on the alliance chain to obtain a comparison result;

[0100] As described in the following steps, when the comparison result is passed, the data recipient stores the transaction information into the local system of the data recipient.

[0101] As an example, see Figure 2-5 , the data recipient queries the transaction from the alliance chain, obtains the hash value of the copy on the chain, and verifies the authenticity and integrity of the personal information copy file through hash value comparison. At the same time, from the alliance chain, through the identity information of the data subject on the alliance chain, check the identity of the transaction initiator (that is, the identity of the data subject) to determine the reliability of the copy source. The alliance chain is used to authenticate the identity of the personal information processor, solve the problem of different data processors requiring multi-party trust, and ensure the reliability of the source of personal information.

[0102] After the verification of the copy of the personal information file is passed, the data recipient adds the information in the copy of the personal information into the system of this organization through automated or manual means, thereby achieving the purpose of transferring personal information from organization A to organization B.

[0103] The present invention uses blockchain to preserve electronic evidence. Through technical means such as electronic signatures, trusted timestamps, hash value verification, blockchain data structures, etc., it can reliably ensure that the content of electronic evidence remains intact (adding endorsements and changes in form during data exchange, storage and display do not affect the integrity) and has not been changed (maintaining identity) since its formation, and can be recognized and trusted.

[0104] During the transfer process, the data sender shall ensure that the copy of personal information will not be illegally tampered with, damaged or leaked from the data sender to the data subject. The data receiver shall ensure the security of personal information from the moment the copy file is received by the individual to the moment the transferred personal information is stored in the institution's own system. The copy file and personal information shall be kept safe, ensuring that the file is only accessed by authorized personnel or programs and is not illegally tampered with, damaged or leaked. After the copy information is imported, it is advisable to provide individuals with a way to query it.

[0105] It should be noted that the file format and interface implementation for exporting and importing personal information by the data sender and the data receiver are defined by the organization itself and are not limited by the present invention.

[0106] The personal information copy of the present invention is provided by the data subject user himself to other personal information processors. Compared with the direct transmission of personal data between different personal information processors, it has the following advantages:

[0107] (1) Proof that the data transfer activity has been fully informed and authorized by the user.

[0108] (II) Different personal information processors do not need to negotiate the specific data format in advance, and the sender and receiver's systems do not need to be forcibly adapted, saving a lot of custom development work. The personal information processors on both sides only need to agree on a common data format, such as json, XML, etc., to ensure that the data copy is stored in a machine-readable form.

[0109] However, there are the following problems: the copy is not trusted and there is a risk of the copy being tampered with, forged or damaged.

[0110] Trust issues can generally be resolved through digital certificates. Digital certificates require a CA that is recognized by all personal information processors, and the CA issues the certificate. If multiple personal information processors are involved, it is difficult to reach a consensus. The present invention proposes to solve the multi-party trust problem through blockchain technology, and ensure that the copy of personal information submitted by the user is authentic and not tampered with.

[0111] Due to the access mechanism of the alliance chain, the institutions that join the alliance chain have passed the real-name authentication, ensuring that the transaction (the content mainly includes the hash value of the copy of personal information) is issued by the real-name authenticated institution, solving the problem of multi-party trust. Although the copy of personal information is transmitted by the user himself, the tamper-proof feature of the blockchain ensures that the copy of personal information will not be tampered with during the transmission process from institution A to institution B. If tampered, it will be easily discovered.

[0112] Example 2

[0113] Reference Figure 6, shows a method for realizing data portability based on blockchain technology, the method involving a consortium chain, a data subject, a data sender, and a data receiver;

[0114] include:

[0115] S610: When the data subject initiates the transaction request to the data sender, the data subject accepts the identity verification of the data sender; wherein the data sender is used to accept the transaction request of the data subject and verify the identity of the data subject;

[0116] S620: When the identity authentication of the data subject is passed, the data subject waits for the data sender to send corresponding transaction information; wherein the data sender is further used to provide the transaction information of the data subject to the data subject and publish the transaction information to the alliance chain; the alliance chain is used to receive the transaction information sent by the data sender;

[0117] S630: The data subject receives the corresponding transaction information sent by the data sender and accepts the identity verification of the data receiver;

[0118] S640. When the identity authentication of the data subject is passed, the data subject sends the transaction information to the data recipient; wherein the data recipient is used to receive the transaction information sent by the data subject, and initiate a data matching request to the alliance chain; the alliance chain is also used to accept the data matching request of the data recipient, and send the transaction information matching the data matching request to the data recipient; the data recipient is also used to compare the transaction information sent by the data subject with the transaction information matched from the alliance chain, and store the transaction information that has passed the comparison.

[0119] Below, a method for implementing data portability rights based on blockchain technology in this exemplary embodiment will be further explained.

[0120] As an example, an institution or industry association creates a personal information transfer alliance chain, and the data sender and the data recipient have both joined the alliance chain through real-name authentication; the data subject makes a request for data transfer to the data sender, and the data sender verifies the identity of the data subject, responds to the individual's request, provides a copy of the personal information in electronic form (encrypted or unencrypted), and publishes a transaction on the alliance chain at the same time, and the transaction content is the hash value of the personal information copy file or content.

[0121] The data subject downloads a copy of the above personal information from the data sender and can view the contents of the copy but cannot modify it.

[0122] The data subject passes the identity authentication of the data recipient and submits the copy of the above personal information to the data recipient in the manner provided by the data recipient. After the data recipient obtains the copy of the personal information, it calculates the hash value of the copy file. The data recipient queries the transaction from the alliance chain, obtains the hash value of the copy on the chain, and verifies the authenticity and integrity of the copy file by comparing the hash values. At the same time, the identity of the transaction initiator is checked from the chain to determine the reliability of the copy source. After the verification of the copy file is passed, the data recipient adds the information in the copy to the system of the institution through automated or manual methods.

[0123] It should be noted that the method of this embodiment is basically similar to that of Embodiment 1, so the description is relatively simple, and the relevant parts may refer to the partial description of Method Embodiment 1.

[0128] S720. When the data subject passes the identity authentication of the data sender, the data sender sends the transaction information of the data subject to the data subject and the alliance chain; wherein the data subject is also used to send the transaction information provided by the data sender to the data receiver; the alliance chain is used to receive the transaction information sent by the data sender; the data receiver is used to receive the transaction information sent by the data subject and initiate a data matching request to the alliance chain; the alliance chain is also used to receive the data matching request from the data receiver, and send the transaction information matching the data matching request to the data receiver; the data receiver is also used to compare the transaction information sent by the data subject with the transaction information matched from the alliance chain, and store the compared transaction information.

[0132] As described in the following steps, the data sender sends the transaction information to the data subject;

[0133] As described in the following steps, the data sender sends the hash value corresponding to the transaction information to the alliance chain.

After the data recipient obtains the copy of the personal information, it calculates the hash value of the copy file. The data recipient queries the transaction from the alliance chain, obtains the hash value of the copy on the chain, and verifies the authenticity and integrity of the copy file by comparing the hash values. At the same time, the identity of the transaction initiator is checked from the chain to determine the reliability of the copy source. After the verification of the copy file is passed, the data recipient adds the information in the copy to the system of the institution through automated or manual methods.
