Referring to fig. 1, fig. 1 is a flow chart of an information protection method according to an embodiment of the application. The embodiment of the application provides an information protection method, which comprises the steps of S110, S120, S130, S140 and S150, wherein:
step S110: and reading the exhibition information to be stored.
The exhibition information to be stored is transmitted through a preset security protocol.
Specifically, the preset security protocol may be any one of SSL (Secure Socket Layer) security protocols, UDP protocol and TLS protocol, which is helpful to improve the security of the display information to be stored in the transmission process of the display information to be stored. For example, SSL is a security protocol that provides a secure connection for TCP (Transmission Control Protocol) -based application layer protocols, and SSL is interposed between the fourth and seventh layers of the TCP (Transmission Control Protocol) transmission control protocol/IP (Internet Protocol) internet protocol stack, mainly providing privacy, integrity and authentication, and is a protocol that provides a secure channel between two machines, which has the functions of protecting data transmissions and identifying communication machines. The preset security protocol can be modified according to the requirements, and the specific security protocol is not particularly limited in the embodiment of the application, so long as the probability of losing or being tampered with information in the transmission process of the exhibition information to be stored can be reduced.

Specifically, after the exhibition information to be stored is obtained, the obtained exhibition information to be stored is encrypted, and then the encrypted exhibition information is stored, so that the safety of the exhibition information in the storage process is improved. The encryption mode of the exhibition information to be stored can be through MD5 (Message-Digest Algorithm 5), SHA (Secure Hash Algorithm secure hash Algorithm) and HMAC (HASH MESSAGE Authentication Code hash information authentication code), wherein the principle of encrypting the exhibition information to be stored by using the HMAC Algorithm is that a fixed-length value is generated by using a public function and an initial key as an authentication identifier, and the generated authentication identifier is used for encrypting the exhibition information to be stored. In the embodiment of the application, the manner of encrypting the exhibition information to be stored is not particularly limited, as long as the encryption operation of the exhibition information can be realized before the storage.
Step S130: writing the encryption exhibition information into a plurality of preset storage units according to a preset sequence, wherein the storage units at least comprise cloud ends.
Specifically, the storage paths of the plurality of storage units are different, and the storage paths can be a central control storage unit and a broadcasting control storage unit, and the preset sequence when the encryption exhibition information is written in can be modified according to requirements, for example, the storage paths are written in the central control storage unit first and then in the broadcasting control end storage unit, and the number of the storage units is at least two. When the terminal reads the exhibition information, the terminal also reads the exhibition information according to the preset sequence, and the encryption exhibition information is written into the plurality of storage units, so that the probability of information loss of the encryption exhibition information in the storage process is reduced. The preset sequence can be modified according to the requirement, and in the embodiment of the application, the sequence of the cloud end is at the last position.
Step S140: and after receiving the access request of the terminal equipment, acquiring the IP address of the terminal equipment, and judging whether the IP address meets the preset access standard.
Specifically, the access request of the terminal device at least includes access request information and an IP address of the terminal device, and the preset access standard may be modified according to requirements, for example, whether the access behavior is a malicious attack is determined according to the number of access times of the IP address in a preset time. If malicious attack exists, the storage unit is easy to crash, and further the stored information is lost or tampered.
Step S150: when the IP address meets the access standard, the decryption information is sent to the terminal equipment so that the terminal equipment can obtain exhibition information according to the decryption information.
Specifically, the decryption information may be pre-stored or automatically generated, and the decryption information may be sent when the IP address of the access is detected to match the access identifier. The encryption exhibition information can be decrypted based on the decryption information, and for example, when the encryption method is the hash information authentication code, the content stored in the decryption information is an authentication identifier which is a value of a fixed length generated by the public function and the initial key and an initial key used in encryption, and the encryption exhibition information is decrypted by the initial key and the authentication identifier.
According to the embodiment of the application, the security of the exhibition information to be stored in the transmission process is improved by reading the exhibition information to be stored which is transmitted through the preset security protocol, the read exhibition information to be stored is encrypted, and then the encrypted exhibition information is stored to a plurality of positions according to the preset sequence, so that the security of the exhibition information in the storage process is improved; according to the access request sent by the terminal, the IP address of the terminal is obtained, whether the IP address sent by the terminal meets the access standard or not is judged, the safety of the exhibition information when the IP address meets the access standard is improved, when the IP address meets the access standard, the decryption information is sent to the terminal device, the terminal device is convenient for decrypting the encryption exhibition information according to the decryption information so as to obtain the exhibition information, the probability that the exhibition information is lost or tampered in the transmission, storage and reading processes is reduced, and the safety of the exhibition information is further improved.
Further, in order to improve the security of the exhibition information during reading, in step S140, the IP address of the terminal device is obtained, and whether the address meets the preset access standard is determined, which specifically may include step S1401 (not shown in the drawing), step S1402 (not shown in the drawing), step S1403 (not shown in the drawing), and step S1404 (not shown in the drawing), wherein:
step S1401: the access times and access time of the IP address of the terminal equipment are obtained.
Specifically, when the terminal device reads the exhibition information, the IP address corresponding to the terminal device accesses the electronic device once, and at this time, the number of accesses and the access time corresponding to the IP address of each accessing electronic device need to be recorded.
Step S1402: based on the access times and access time of the IP address of the terminal equipment, the total access times of the IP address in a preset time period are calculated.
Specifically, the preset time may be one hour or two hours, and the specific duration is not specifically limited. As long as the number of accesses to the same IP address over a period of time can be counted.
Step S1403: if the total number of accesses in the preset time period does not exceed the preset threshold value, the IP address is determined to accord with the access standard.
Step S1404: if the total access times in the preset time period exceeds the preset threshold, determining that the IP address does not meet the access standard, and prohibiting the IP address which does not meet the access standard from accessing again.
Specifically, the preset threshold value can be modified according to the requirement, and can be a built-in numerical value or can be manually input. The access times of the same IP address in a preset time period are controlled to screen malicious IP addresses, and if the IP addresses with the access times exceeding a preset threshold value in the preset time period exist, the storage unit is easy to collapse, so that the situation that encryption exhibition information is lost and the like is caused.
According to the embodiment of the application, the times of accessing the IP address of the electronic equipment can be monitored, whether the IP address which does not meet the access standard exists or not is determined by counting the times of accessing the same IP address in the preset time period, and the IP address which does not meet the access standard is forbidden to access, so that the memory cell abnormality caused by malicious access is reduced, and the security in the process of reading the encryption exhibition information is further improved.
Further, in step S1404, prohibiting the IP address that does not meet the access standard from being accessed again may include adding the IP address that does not meet the access standard to the forbidden list of the firewall.
Specifically, the IP address which does not meet the access standard is written into the forbidden list of the firewall, and when the IP address in the forbidden list accesses the electronic device again, the forbidden address is intercepted by the firewall and cannot be accessed again.
In another possible implementation manner, the manner of prohibiting the re-access of the IP address which does not meet the access standard may be that the access of the IP address which does not meet the access standard is prohibited by performing an abnormal suffix marking on the IP address which does not meet the access standard, recording the abnormal suffix marking, and not receiving the access request sent by the IP address carrying the abnormal suffix marking.
According to the embodiment of the application, the IP addresses which do not accord with the access standard can be written into the forbidden list of the firewall, so that the IP addresses which do not accord with the access standard are forbidden to be accessed again, and the overall safety is improved.
In the embodiment of the present application, step S150 may specifically include step S1501 (not shown in the accompanying drawings), step S1502 (not shown in the accompanying drawings), and step S1503 (not shown in the accompanying drawings), where:
step S1501: and acquiring account information corresponding to the terminal equipment, and judging whether the account information corresponding to the terminal equipment has access rights according to a preset access list.
The preset access list can be modified according to requirements, for example, accounts of staff such as a responsible person and a host of an exhibition can be accessed, and account information of related staff is stored in the access list. When the IP address of the access electronic equipment accords with the access standard, whether the account information logged in by the terminal which accords with the IP address of the access standard has access authority is further judged, and the account with the access authority can read the encrypted exhibition information.
Step S1502: when account information corresponding to the terminal equipment has access rights, a decryption identifier is obtained, and a final key is determined from a preset identifier table based on the decryption identifier, wherein the decryption identifier is obtained by analyzing decryption information sent by the received electronic equipment by the terminal equipment.
Step S1503: and sending the final key and the encrypted exhibition information to the terminal equipment so that the terminal equipment can decrypt the encrypted exhibition information according to the final key to obtain the exhibition information.
