The network may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few. It should be understood that the number of terminals, networks, and servers in fig. 3 is merely illustrative. There may be any number of terminals, networks and servers, as desired for the reality.

Next, the two-dimensional code generation method provided in the embodiment of the present application is described with reference to the virtual reality display device shown in fig. 1, the application scenario of the two-dimensional code generation method shown in fig. 2, and the system architecture of the two-dimensional code generation method shown in fig. 3. Fig. 4 exemplarily shows a flowchart of a two-dimensional code generation method provided in an embodiment of the present application. As shown in fig. 4, the method for detecting surface defects of an object may include at least the following steps:
s401, receiving a two-dimensional code trigger signal to generate trigger data.
The two-dimensional code triggering signal is used for representing a signal generated by triggering when a user needs to use a two-dimensional code in application software, for example, when the user purchases a commodity, the user needs to provide the two-dimensional code which can be used for commodity payment to a merchant, the user needs to start a corresponding application program in an electronic information display screen of the virtual reality display device, after the application program is initialized, a payment option is clicked, and the virtual reality display device can receive the two-dimensional code triggering signal to generate triggering data.
S402, generating a two-dimensional code based on the trigger data.
Possibly, the application software that generates the two-dimensional code requires a "two-dimensional code generator" tool, which works on the principle of using a matrix of numbers arranged with 1's and 0's to produce the verification function.
Specifically, the two-dimensional code records data symbol information by black and white alternate patterns distributed on a plane (in a two-dimensional direction) according to a certain rule by using a certain specific geometric figure; the concept of '0' and '1' bit stream which forms the internal logic base of computer is skillfully utilized in coding, a plurality of geometric shapes corresponding to binary system are used for representing literal numerical information, and the information is automatically read by an image input device or an optoelectronic scanning device to realize automatic information processing, and the method has some commonalities of bar code technology: each code system has its specific character set; each character occupies a certain width; has certain checking function and the like. Meanwhile, the method has the characteristics of automatic identification function of information of different rows, processing of figure rotation change and the like. The two-dimensional code can express information in both the horizontal and vertical directions, and thus can express a large amount of information in a small area.
And S403, the two-dimensional code is projected to a fixed interface of an external environment through a projection unit.
The external environment can be a fixed interface which is convenient for a merchant to scan and recognize codes, such as a wall surface and a counter of the merchant.
Possibly, the projection unit may include an image display element and a lens. The projection unit first irradiates light to the image display element to generate an image, and then projects the image through the lens. The image display element of the projection unit may include both a transmissive type that generates an image using light transmission and a reflective type that generates an image using reflected light. However, in either type, the light from the projection lamp is divided into three colors, red, green, and blue, and images of various colors are generated. Since the element itself can perform only a single color display, 3 elements are used to generate 3 color components, respectively. Then the 3 color images are synthesized into an image through a prism, and finally the image is projected to a fixed interface through a lens to form a two-dimensional code.
Illustratively, after the cashier finishes scanning all the articles, the amount to be paid is generated according to the price information of the articles calculated by the cash register device, and the two-dimensional codes put in by the consumer through the VR glasses are identified by a scanner carried by the cash register device to finish the payment process.
In the embodiment of the application, the trigger data can be generated by receiving the two-dimensional code trigger signal; generating a two-dimensional code based on the trigger data; and the two-dimensional code is projected to a fixed interface of an external environment through a projection unit. Therefore, the commodity payment process is realized by using the virtual reality display equipment, and the user experience is optimized.
In some embodiments, before generating the two-dimensional code based on the trigger data, an embodiment of the present application may further include: the trigger data is encrypted to generate encrypted trigger data.
Fig. 5 exemplarily shows a flowchart of a two-dimensional code generation method provided in an embodiment of the present application. As shown in fig. 5, the two-dimensional code generation method may include at least the following steps:
s501, receiving a two-dimensional code trigger signal to generate trigger data.
Specifically, S501 is identical to S401, and is not described herein again.
S502, the trigger data is encrypted to generate encrypted trigger data.
Possibly, the embodiment of the present application may use a DES (Data Encryption Standard, american Data Encryption Standard) algorithm or an RSA algorithm (RSA algorithm), or may use a mixed algorithm of DES and RSA.
S503, the encrypted trigger data is decrypted to obtain decrypted trigger data.
In particular, DES is a block encryption algorithm, and a typical DES uses 64-bit blocks to encrypt data, and the same algorithm is used for encryption and decryption. Its key length is 56 bits (since every 8 th bit is used as parity), and the key can be any number of 56 bits and can be changed at any time.
The algorithm framework for DES encryption is as follows:
firstly, a set of encryption keys is generated, a 64-bit-long password is obtained from a user, and then a set of 16 encryption keys is formed through halving, shifting, selecting and iterating and is used in each round of operation.
DES operates on a 64-bit (bit) plaintext block M, which is permuted to M0 by an initial permutation IP. M0 is divided into left and right halves m0 ═ L0, R0, each 32 bits long. Then 16 rounds of exactly the same operations (iterations) are performed, these operations being called functions f, the data being combined with the corresponding key during each round.
In each round, the key is shifted by 48 bits, and then the key is selected from the 56 bits. The right half of the data is expanded to 48 bits by an expansion permutation and replaced with new 48 bits of data by an exclusive or operation, which is then packed and permuted to 32 bits. These four steps constitute the function f. Then, the output of the function f is combined with the left half by another exclusive-or operation, the result becomes a new right half, and the original right half becomes the new left half. This operation was repeated 16 times.
After 16 iterations, the left and right halves are combined together and subjected to a final permutation (data grooming), thus completing the encryption process.
Specifically, the algorithm of RSA is described as follows:
1. RSA generates public and private key pairs
Specific examples teach how to generate a key pair
1.1, randomly selecting two unequal prime numbers p and q.
alice selects 61 and 53. (in practice, the greater these two prime numbers, the harder it is to break.)
1.2, calculating the product n of p and q. n 61 × 53 3233
The length of n is the key length. 3233 the binary number is 110010100001, which has a total of 12 bits, so this key is 12 bits. In practical applications, the RSA key is generally 1024 bits, and in important cases 2048 bits.
1.3 computing the Euler function of n

And e and
Figure BDA0002860893980000076
are relatively prime. alice is between 1 and 3120 and has randomly chosen 17. (in practice, 65537 is often chosen.)
1.5, calculate e for
Figure BDA0002860893980000077
Modulo element d. That is, the number of the key used for decryption, the so-called "modulo element", is the integer d that allows ed to be decrypted

The remainder of the division is 1. ed ≡ 1 (mod)

) alice finds 2753, i.e., 17 x 2753mode 3120-1.
1.6, encapsulating n and e into a public key and encapsulating n and d into a private key.
In alice, since n is 3233, e is 17, and d is 2753, the public key is (3233,17) and the private key is (3233,2753).
2. RSA encryption
Firstly, bit string grouping is carried out on plaintext, so that the decimal number corresponding to each group is smaller than n, then encryption is carried out on each group m in sequence, a sequence formed by ciphertext of all groups is the encryption result of an original message, namely m satisfies 0< ═ m < n, and then the encryption algorithm is as follows: c ≡ m ^ e mode n; c is ciphertext, and 0< ═ c < n.
3. RSA decryption
For ciphertext 0< ═ c < n, the decryption algorithm is: m ≡ c ^ d mod n.
Specifically, the hybrid algorithm of DES and RSA is described as follows:
1. encryption scheme basic principle of DES and RSA mixed encryption algorithm
The method comprises the steps of encrypting a plain document by using a DES encryption algorithm method, and simultaneously encrypting a DES key by using an RSA encryption algorithm method.

And performing DES decryption on the ciphertext c by using the generated key k to generate a plaintext file.
And S504, generating a two-dimensional code based on the decrypted trigger data.
Specifically, S504 is identical to S402, and is not described here.
And S505, the two-dimensional code is projected to a fixed interface of an external environment through a projection unit.
Specifically, S505 is identical to S403, and is not described herein again.
In a specific example, the application program sends a payment request to the background, the background receives the payment request, the two-dimensional code is generated through a payment link by inquiring from the database, and then the two-dimensional code is sent to the front end, and the front end receives data and displays the data into the two-dimensional code. The VR glasses receive the encrypted trigger data, generate the two-dimensional code through decryption, and finally project the two-dimensional code onto the fixed interface, the application program needs to inform the driver to open the projection unit, and after the projection unit is started, the current interface is projected onto the fixed interface.
Therefore, the embodiment of the application can prevent the trigger data from being stolen by criminals by encrypting the transmitted trigger data, thereby protecting the safety of the fund account of the user and improving the user experience.
In some embodiments, after the step of generating the two-dimensional code based on the trigger data, before the two-dimensional code is released to a fixed interface of an external environment through a projection unit, the embodiment of the present application may further include the step of: receiving a releasing instruction triggered by a user; and starting the projection unit based on the throwing instruction.
The projection instruction may correspond to a first projection mode or a second projection mode, and specifically, the output directions of the output light in the first projection mode and the output directions of the output light in the second projection mode are different. The projection instruction is generated by the virtual reality display device according to the received user operation, for example, the user performs operation control on a physical key or a graphical interactive interface on the virtual reality display device, the virtual reality display device collects the operations and generates a corresponding projection instruction, further, the projection unit can monitor the current posture or posture change of the virtual reality display device by using the monitoring unit and send the monitored information to the virtual reality display device to generate a related projection instruction.
In some embodiments, the two-dimensional code in the display interface may be further projected to a fixed interface of an external environment through the projection unit.
Wherein, the projection unit may be an infrared laser device to project the virtual input unit of infrared rays onto a fixed interface of an external environment.
