Referring to fig. 1, fig. 1 provides an electronic device, which may specifically include: the device comprises a processor, a memory, a camera and a display screen, wherein the components can be connected through a bus or in other ways, and the application is not limited to the specific way of the connection. In practical applications, the computer device may be specifically a smart phone, a personal computer, a server, a tablet computer, a smart television, and the like.
If the block chain in the application relates to digital currency, the digital currency refers to digital RMB occurring in China RMB.
Information change in electronic commerce belongs to very common verification information, part of information in the information change is not changed, but some information is changed, for example, information such as an identity card number, a birth date, a sex, a name family and the like in identity verification is not invariable, but information such as a name, an address and the like of an identity card is variable, and how to change the information becomes a problem to be solved in the electronic commerce.
Referring to fig. 2, fig. 2 provides a block chain e-commerce information change method, which may be executed in the electronic device shown in fig. 1, and the method shown in fig. 2 includes the following steps:
s200, the electronic equipment acquires information to be changed of electronic commerce, and classifies and identifies the information to be changed to determine invariable information and variable information in the information to be changed;
the classification identification may be implemented by a classifier, such as a support vector machine, a neural network model, or the like, to determine variable information and non-variable information in the information to be changed.
Taking the identity information as an example, the immutable information may include: the identification card number, the date of birth, the sex, the name and other information, and the variable information specifically comprises: name, address, issuing authority, etc.
Of course, the information to be changed may be other information, such as a business license, a work permit, and the like.
Step S201, the electronic device performs calculation on the immutable information and the variable information respectively to obtain a first hash value (corresponding to the immutable information) and a second hash value (corresponding to the variable information);
the above calculation mode may be hash calculation, and the specific implementation mode may refer to a calculation mode of a hash value, which is not described herein again.
Step S202, the electronic device sends the first hash value and the second hash value to other devices of the block chain, when the other devices inquire a third hash value identical to the first hash value and do not inquire a fourth hash value identical to the second hash value, the other devices replace variable information mapped by the third hash value with variable information corresponding to the second hash value, and the other devices replace the fourth hash value paired with the third hash value with the second hash value to complete information change of electronic commerce.
The other device may be a trusted device in the blockchain, and the other device may be other electronic devices, such as computers, servers, and the like.
According to the technical scheme, electronic equipment acquires information to be changed of electronic commerce, and classifies and identifies the information to be changed to determine invariable information and variable information in the information to be changed; the electronic equipment respectively calculates the invariable information and the variable information to obtain a first hash value (corresponding to the invariable information) and a second hash value (corresponding to the variable information); and when the other equipment queries a third hash value which is the same as the first hash value and does not query a fourth hash value which is the same as the second hash value, the other equipment replaces variable information mapped by the third hash value with variable information corresponding to the second hash value and replaces a fourth hash value paired with the third hash value with the second hash value to complete information change of the electronic commerce. According to the method and the device, whether the variable information changes or not is pointed by the hash value of the invariable information, and then the information is simplified and the flow is improved, so that the variable information in the information to be changed can be independently changed in a block chain mode, repeated change of the invariable information is avoided, change of part of information in the block chain is realized, the information change efficiency is improved, and the information change cost is reduced.
For the information change, the existing change to the whole, for example, after the identity document is reissued, the identity document is replaced, the change causes more changed data in the block chain, because most contents in the information to be changed of the electronic commerce are invariable information, the whole change increases the data amount in the block chain, and increases the uplink cost (the uplink data of the block chain is charged according to the size of the data amount), therefore, the application processes the invariable information and the variable information in the information to be changed respectively, and establishes the mapping between the hash value of the invariable information and the variable information, so that the corresponding variable information can be inquired through the invariable hash value, and further determines whether the variable information is changed through the comparison of the hash values, when the variable information is changed, the change of the information is completed through the replacement, therefore, the data volume of the changed information is reduced, the information is convenient to change, the information changing efficiency is improved, and the cost is reduced.
For example, the method may further include, before step S200:
the electronic device verifies the target object, and if the verification is passed, step S200 and subsequent steps are executed, the verification of the target object may be performed in a biometric verification manner, such as a human face, a fingerprint, a voiceprint, and the like, and the present application does not limit the specific manner of the verification.
The target object is verified, so that the reliability of the information to be changed can be improved, the safety of information change is further improved, and malicious change of irrelevant personnel is avoided.
For example, the verifying the target object by the electronic device may specifically include:
the electronic equipment collects a face picture of a target object, performs feature extraction on the face picture to obtain input data, performs n-layer convolution operation on the input data to obtain an operation result, performs subtraction operation according to the operation result and a template operation result to obtain a difference value, determines that verification does not pass if the difference value is larger than a verification threshold, and determines that verification passes if the difference value is smaller than the verification threshold.
For example, if the input data is an input matrix, the performing n-layer convolution operation on the input data to obtain the operation result may specifically include:
performing a first layer of convolution operation on the input matrix to obtain a first layer of convolution result, and performing a next layer of convolution operation on the first layer of convolution result as a next layer of input matrix to obtain a next layer of convolution result until n layers of convolution operation are performed to obtain an operation result; the obtaining of the first layer convolution result by performing the first layer convolution operation on the input matrix may specifically include:
obtaining convolution kernel size [ y ] of a first layer of convolution operation, cutting an input matrix by taking [ y ] as the size of a sliding window to obtain alpha cutting matrixes, wherein the size of the cutting matrixes is [ y ], comparing the alpha cutting matrixes to determine the number of the cutting matrixes with completely same element values, obtaining the maximum value beta in the number of the completely same cutting matrixes, and if the beta is larger than a first threshold value, constructing a bitmap (bitmap) of the beta cutting matrixes relative to the alpha cutting matrixes; traversing each cutting matrix in the alpha cutting matrices, wherein if the cutting matrix belongs to the beta cutting matrices, the value corresponding to the bitmap is 1, and if the cutting matrix does not belong to the beta cutting matrices, the value corresponding to the bitmap is 0; performing convolution operation on one cutting matrix in the beta cutting matrixes and the convolution kernel to obtain a calculation resultβWhen the convolution operation is executed by the alpha cutting matrixes and the convolution kernel, the value of the ith cutting matrix in the bitmap is extracted, and if the value is equal to 1, the calculation result is directly outputβIf the value is equal to 0, performing convolution operation on the ith cutting matrix and the convolution kernel to obtain a calculation resultiAnd traversing the alpha cutting matrixes to execute convolution operation to obtain a first layer of convolution result. The convolution operation of other layers (subsequent layers) can also refer to the above manner, and is not described herein again.
The following describes a bitmap manner by using an actual example, which may specifically include: if the number of the α cutting matrixes is 1000, the bit corresponding to the bitmap is also 1000 bits, and if β is 100 and the β cutting matrixes are located in the first 100 of the 1000 cutting matrixes, the first 100 bits of the bitmap are 1, and the last 900 bits of the bitmap are 0. It should be noted that the positions corresponding to the β cutting matrices are only examples, and may be different in practical applications.
The cutting matrices with identical element values may specifically include: the value of each corresponding position of the 2 cutting matrices is the same.
The first threshold value is generally large, for example, 50, 100, 200, etc.
The principle of the scheme specifically comprises the following steps: the convolution operation is the same result for the same cutting matrix and convolution kernel (the value of the convolution kernel is the same), but the prior convolution operation is not distinguished and is directly calculated, and for a human face picture, the input matrix can be the RGB value of a pixel point, and for the human face picture, the RGB value of most pixel points is the RGB value of the skin, so the probability that the element values are the same is higherβTherefore, the calculation amount can be reduced, and the calculation efficiency can be improved. The above calculation resultsβAnd the calculation resultiThe subscripts in are merely labels to distinguish the results of the calculations.
