In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
Fig. 1 is a flowchart of an implementation of a fingerprint security login method of a cloud computer according to an embodiment of the present invention, where an execution subject is a local terminal, and the detailed description is as follows:
step 101, fingerprint data of the same finger of a user are collected for a plurality of times, and the fingerprint data are encrypted to obtain fingerprint encrypted data.
The local terminal can acquire fingerprint data of the same finger of the user for multiple times by adopting the local fingerprint module, wherein the fingerprint data can be fingerprint images or fingerprint feature points.
In order to ensure the integrity of fingerprint data, fingerprint images of all angles of the fingerprint are required to be acquired, and if the detected area overlapping rate of the fingerprint images is larger than a first preset value, a user is notified to acquire again.
Alternatively, the present invention is not limited to the value of the first preset value, for example, the first preset value may be 95%, 96% or 97%. Fingerprint data with low overlapping rate are collected, 360-angle fingerprint data can be better obtained, and the fingerprint unlocking rate of the algorithm is improved.
In one possible implementation, encrypting the fingerprint data to obtain fingerprint encrypted data includes:
Obtaining a salt value and a secret key, and generating a target byte array according to the salt value and the secret key;
alternatively, a salt value composed of irregular characters is acquired, and a randomly generated integer array key is acquired.
The salt values belong to random values. The random number generated by the system for combining with the user password during the registration of the user can comprise random upper and lower case letters, numbers and characters, and the number of the digits can be different according to requirements and is called a salt value, and is called a salt value. And the salt value is added for the user password, so that the encrypted ciphertext is more rarely used and is not easy to crack. Even if a hacker has a value queried by the ciphertext, the password added with the salt value is not the password set by the user.
Optionally, a random number is generated, the number of bits required for each movement of the random number is generated into a key, and the key is an integer array.
Because the salt value consists of irregular characters and the password is an integer array, the two can only generate byte arrays, wherein in the byte arrays, taking ASCII codes as an example, one English letter (without case) occupies one byte space, and one Chinese character occupies two bytes space. The symbols: english punctuation occupies one byte and Chinese punctuation occupies two bytes. Examples: english period "," 1 byte in size, chinese period ". "size of 2 bytes".
Acquiring a current byte of the salt value and acquiring the current byte in the key;
performing exclusive OR operation on the two current bytes to obtain first data;
taking the next byte of the current byte of the salt value as the current byte and taking the next byte of the current byte in the secret key as the current byte, jumping to the step of performing exclusive-or operation on the two current bytes to obtain first data until all bytes of the salt value and all bytes of the secret key complete exclusive-or operation;
and generating a target byte array according to all the first data.
And performing exclusive-or operation on the bytes in the salt value and the data in the secret key, and continuously cycling until all exclusive-or operations on the data corresponding to the bytes in the salt value are completed, so as to obtain a plurality of first data, and sequentially combining the first data to obtain a target byte array for encrypting the fingerprint data.
Wherein the number of bytes in the salt value is the same as the number of bytes in the key.
Optionally, processing the fingerprint data according to a preset rule to obtain primary fingerprint encrypted data, including:
optionally, the fingerprint data is replaced according to a preset mapping rule among the pre-built letters, numbers and characters, so as to obtain primary fingerprint encrypted data. Here, the preset mapping rule is not limited in the present invention, and may be set according to specific requirements. For example, the letter a corresponds to A, B corresponds to B, … …,1 corresponds to-! 2 corresponds to #,6 corresponds to #, etc. For replacing the fingerprint data, the fingerprint data can be encrypted once, so that the safety of the fingerprint data is effectively ensured.
Optionally, encrypting the fingerprint data according to an asymmetric encryption algorithm to obtain primary fingerprint encrypted data;
the commonly used asymmetric encryption algorithm is an RSA encryption algorithm, and the encryption steps of the RSA encryption algorithm comprise:
(1) Selecting two large prime numbers p and q;
(2) Calculating the product of the two large primes by n=p×q, wherein n represents the product and p and q represent two different large primes respectively;
(3) Calculating to obtain an Euler function of n through z= (p-1) × (q-1), wherein z represents the Euler function value of n;
(4) Selecting a number which is compatible with z in the interval (1, z), and defining the selected number as e, wherein e represents an encryption key;
(5) The fingerprint data is regarded as plaintext and divided into k-bit data blocks P, where k represents the satisfaction of z k <A maximum integer of n;
according to C=P e (mod n) encrypt the plaintext, where P represents a block of data of the plaintext and C represents ciphertext of P.
And (3) encrypting the fingerprint data through the steps (1) to (5), and replacing the obtained ciphertext with plaintext.
Optionally, the fingerprint data is encrypted according to a symmetric encryption algorithm to obtain primary fingerprint encrypted data.
A common symmetric encryption algorithm is the advanced encryption standard (Advanced Encryption Standard, AES) algorithm, the encryption step of AES comprising:
And performing byte substitution, row displacement, column confusion and round key addition on the fingerprint data to obtain primary fingerprint encryption data.
And carrying out preset operation on the target byte array and the primary fingerprint encryption data to obtain the fingerprint encryption data.
Optionally, the preset operation is not limited in the present invention, and may be set according to actual needs, for example, an exclusive-or operation, a merging operation, or a merging and reversing operation may be adopted in the present invention.
When the exclusive or operation is adopted, the cipherer text=test≡key is adopted to obtain fingerprint encrypted data, wherein the key represents a target byte array, the test represents primary fingerprint encrypted data, and the cipherer text represents encrypted data.
When the combination operation is adopted, a programming algorithm can be adopted to combine the two byte arrays, and similarly, when the combination and inversion operation is adopted, the programming algorithm is still adopted to combine the two byte arrays, and the combined byte arrays are inverted.
The operation given above has the final purpose of encrypting the fingerprint data, ensuring that the fingerprint data cannot be leaked, and ensuring the data integrity and the security of the fingerprint data in the transmission process.
Optionally, before step 101, the local terminal first logs in the cloud computer account of the user, receives a fingerprint collection instruction sent by the cloud server, and then collects fingerprint data of the same finger of the user for multiple times, and encrypts the fingerprint data to obtain fingerprint encrypted data.
Step 102, a first storage request is sent to a cloud server, wherein the first storage request comprises fingerprint encryption data.
Optionally, the first storage request may further include other bytes corresponding to the transmission channel in addition to the fingerprint encrypted data, so as to ensure smooth transmission of the fingerprint encrypted data.
After receiving a first storage request sent by a local terminal, the cloud server decrypts the fingerprint encrypted data according to the first storage request to obtain fingerprint data, then verifies the fingerprint data, and when the fingerprint data is successfully verified, obtains a login account corresponding to the current user, and stores the fingerprint data and the login account in a database of the cloud server.
Step 103, when the cloud computer corresponding to the cloud server is to be logged in, current fingerprint data of the user is collected, the current fingerprint data is encrypted, and a login request is sent to the cloud server, wherein the login request comprises the current fingerprint encrypted data.
When a user wants to log in the cloud computer, the fingerprint acquisition module firstly acquires current fingerprint data of the user, and encrypts the current fingerprint data by adopting the encryption algorithm described in the step 101 to obtain current fingerprint encryption data.
Optionally, the login request may further include other bytes corresponding to the transmission channel in addition to the current fingerprint encrypted data, so as to ensure smooth transmission of the current fingerprint encrypted data.
After receiving a login request sent by a local terminal, the cloud server decrypts current fingerprint encryption data in the login request to obtain current fingerprint data, and compares the current fingerprint data with fingerprint data in a database of the cloud server; and when the current fingerprint data is consistent with the fingerprint data, sending verification success information to the local terminal.
And 104, unlocking the cloud computer corresponding to the cloud computer account when receiving the verification success information sent by the cloud server.
If the verification of the current fingerprint data is successful, the cloud computer desktop corresponding to the cloud computer account corresponding to the current fingerprint data is unlocked, so that the cloud computer is unlocked by the fingerprint data, the problem that complicated account passwords need to be input for each login in the prior art is avoided, and the login convenience is improved.
The embodiment of the invention provides a fingerprint security login method of a cloud computer, which is characterized in that fingerprint data of the same finger of a user are collected for a plurality of times, and the fingerprint data are encrypted to obtain fingerprint encrypted data; sending a first storage request to a cloud server, wherein the first storage request comprises fingerprint encryption data; when a cloud computer corresponding to a cloud server end is to be logged in, collecting current fingerprint data of a user, encrypting the current fingerprint data, and sending a login request to the cloud server end, wherein the login request comprises the current fingerprint encryption data; and unlocking the cloud computer corresponding to the cloud computer account when the verification success information sent by the cloud server is received. According to the fingerprint safe login method of the cloud computer, provided by the invention, through interaction between the local terminal and the cloud server, unlocking of the cloud computer desktop by the user fingerprint is realized, the problems of inconvenience in inputting an account number and a password and lower safety level in the prior art are solved, the login time is shortened, the user fingerprint can only unlock the cloud computer corresponding to the user cloud computer account number through the correspondence between the fingerprint and the user account number, the safety level of the user is improved, and the user login can be realized more quickly and safely.
Fig. 2 is a flowchart of an implementation of a fingerprint security login method of a cloud computer according to another embodiment of the present invention, where an execution subject is a cloud server, and the detailed description is as follows:
step 201, receiving a first storage request sent by a local terminal, and decrypting the fingerprint encrypted data according to the first storage request to obtain fingerprint data.
The local terminal sends a first storage request to the cloud server, wherein the first storage request comprises fingerprint encryption data.
In one possible implementation, the received fingerprint encrypted data is decrypted to obtain the fingerprint data. Firstly, carrying out reverse preset operation on the fingerprint encryption data to obtain primary fingerprint encryption data and a target byte array.
For example, if the preset operation is an exclusive-or operation, the fingerprint encrypted data is subjected to an exclusive-or operation again, for example, a test=cipherer text key is adopted to obtain the fingerprint data, wherein the key represents a target byte array, the test represents the primary fingerprint encrypted data, and the cipherer text represents the fingerprint encrypted data.
The principle of exclusive-or operation is cipherextkey= (test key)/(key=test).
If the preset operation is the merging operation, splitting the fingerprint encrypted data;
If the preset operation is the combination and inversion operation, the fingerprint encryption data is subjected to the inversion operation and then the splitting operation.
Secondly, decrypting the primary fingerprint encrypted data, for example, if the preset rule is to replace the fingerprint data according to a preset mapping rule among pre-constructed letters, numbers and characters to obtain the primary fingerprint encrypted data, reversely replacing the primary fingerprint encrypted data according to the preset mapping rule to obtain the fingerprint data;
if the preset rule is an asymmetric encryption algorithm, taking RSA as an example, selecting d meeting e×d=1 (mod z), wherein d represents a decryption key; by p=c d (mod n) calculating to obtain fingerprint data.
If the preset rule is a symmetric encryption algorithm, taking AES as an example, performing round key addition, byte substitution inversion, row inversion bit inversion, column confusion inversion and key confusion inversion addition on the primary fingerprint encryption data to obtain fingerprint data.
Step 202, verifying the fingerprint data, if the fingerprint data is successfully verified, obtaining a login account corresponding to the current user, and storing the fingerprint data and the login account in a cloud server database.
Alternatively, the verification of the fingerprint data may be the verification of the head and tail bytes of the fingerprint data and the comparison of the xor checksum and xor check word of the fingerprint data.
In one possible implementation manner, if the verification of the fingerprint data is successful, a login account corresponding to the current user is obtained, and the fingerprint data and the login account are stored in a cloud server database in a corresponding manner, including:
if the first byte and the last byte of the fingerprint data are in a preset header data format, and the exclusive or check sum of the preset bytes in the fingerprint data is the same as the exclusive or check word of the fingerprint data, acquiring a login account corresponding to the current user, and storing the fingerprint data and the login account in a cloud server database.
The exclusive-or checksum of the preset byte and the exclusive-or checksum of the fingerprint data can be the second byte to the N-2 byte in the fingerprint data when the exclusive-or checksum of the preset byte is the same as the exclusive-or checksum of the fingerprint data, and N is a positive integer not less than 5 when the exclusive-or checksum of the second byte to the N-2 byte in the fingerprint data is the same as the data corresponding to the N-1 byte of the fingerprint data.
Optionally, the exclusive-or checksum is obtained by exclusive-or operation from the second byte to the N-2 th byte, and the exclusive-or check word is the next bit of the last byte in the exclusive-or checksum, so that the exclusive-or check word is the data corresponding to the N-1 th byte.
For example, the second to N-2 bytes of fingerprint data are F3, E2, 42 and 3A, where the bytes are 16-bit data.
Starting from the first byte data, performing exclusive OR operation on the rest second byte data to obtain a result; i.e., exclusive-or operation of F3 (1111 0011) with E2 (1110 0010) to obtain result 11 (0001);
performing exclusive OR operation on the last calculation result and the third byte data, and obtaining a result again; i.e., exclusive-or-operate 11 (0001) with 42 (0100 0010), obtain result 53 (0101 0011);
then carrying out exclusive OR operation on the last calculation result and the subsequent data in sequence, and finally obtaining an exclusive OR checksum; i.e. exclusive or 53 (0101 0011) with 3A (0011 1010), an exclusive or checksum 69 (0110 1001) is obtained.
If the data corresponding to the N-1 byte at this time is 69 (0110 1001), the exclusive-OR checksum and the exclusive-OR check word are the same, and the exclusive-OR check is successful.
In one possible implementation manner, if the verification is successful, the login account of the current user is obtained, fingerprint data and the login account are bound, and the fingerprint data and the login account after the binding is successful are stored in a cloud server database.
The fingerprint data and the login account after successful binding are stored in the cloud server database, so that the fingerprint information of the user can be stored in the database, and the fingerprint information of the user is bound with the account information, so that the user can log in by directly adopting the fingerprint.
Optionally, network environment and equipment stability need to be ensured in the transmission process, and the fingerprint data is considered to be complete after successful verification, so that the situations of data loss and the like do not occur in the transmission process.
In one possible implementation manner, when the verification fails, the server starts to record the transmission failure times and sends a retransmission fingerprint instruction to the local terminal;
if the received fingerprint data still fails to be checked, adding one to the transmission failure times, and sending a retransmission fingerprint instruction to the local terminal again until the transmission failure times reach the maximum times, and sending a retransmission fingerprint instruction or a detection transmission channel instruction to the local terminal.
Among these, there may be cases where the verification failure is lost, abnormal fingerprint data, or blocked transmission channels, or the like.
