[0038] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail in the following specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] Example 1

[0040] As attached Figure 1 As shown, this embodiment 1 provides a child safety management method, including the following steps:

[0041] Step 1: Obtain user data; wherein the user data includes location information and vital sign information.

[0042] Specifically, the process of obtaining user data is as follows:

[0043] The location information and vital sign information of the wearer are obtained by using a smart bracelet worn by a child user; wherein the smart bracelet is pre-installed with multiple positioning modules, including a GPS positioning module, a Beidou positioning module, a WiFi module, a LBS module and a low-power Bluetooth BLE module, so as to accurately obtain the location information; wherein a positioning beacon is set at a preset position of the welfare home, so as to communicate with the WiFi module or the low-power Bluetooth BLE module through the positioning beacon to obtain the location information.

[0044] The vital sign information includes dynamic heart rate, body temperature, blood pressure, sleep data and step data.

[0045] Step 2: Use the SHA1withRSA algorithm to encrypt user data and transmit it to the pre-built secure intelligent management platform.

[0046] The encrypted transmission process has the following steps:

[0047] Step 21, using the SHAI algorithm to convert the user data into a string to obtain a string of preset bits; wherein the principle of using the SHAI algorithm to convert the string is specifically as follows: for plaintext of any length, first group it to obtain plaintext groups, so that the length of each group is 512 bits; repeatedly process the plaintext groups until the length of the plaintext groups is mostly a preset value; then, obtain the summary of each plaintext group, that is, obtain a string of preset bits.

[0048] The specific process is as follows:

[0049] Group the user data to obtain several plaintext groups of length 512; divide each plaintext group of length 512 into 16 sub-plaintext groups; where each sub-plaintext group is 32 bits; construct 5 link variables of 32 bits, and record them as link variable A, link variable B, link variable C, link variable D, and link variable E in sequence; expand the 16 sub-plaintext groups into 80 copies; perform 4 rounds of operations on the 80 expanded sub-plaintext groups; perform a summation operation on the link variables and the initial link variables, and use the link variables as the input for the next plaintext group to repeat the above operations; finally, output the data in the 5 link variables, and a string of the preset number of bits is obtained.

[0050] It should be noted that the hash function in the SHA1 algorithm is irreversible and highly collision-resistant, which can ensure that the data will not be tampered with; convert the original message into a string, sign the original string, and convert it into a all-lowercase string after verification as the signature value sign; specifically: receive a piece of plaintext, and then convert it into a piece of ciphertext in an irreversible manner, that is, take a string of input codes, called pre-mapping or information; and convert it into an output sequence with a shorter length and a fixed number of bits, that is, the hash value, also called the message digest or message authentication code.

[0051] Step 22, use the RSA signature algorithm to sign the string of the preset number of bits to obtain encrypted information; among them, the public key KU encryption process of the RSA algorithm is specifically:

[0052] KU=(e,n)

[0053] C = M e mod n

[0054] n = p×q

[0055] The private key KR decryption process of the RSA algorithm is specifically:

[0056] M = C d mod n

[0057] f(n)=(p - 1)×(q - 1)

[0058] (d×e) mod f(n)=1

[0059] Among them, C is the ciphertext; M is the plaintext; e is the public key exponent, e is relatively prime to f(n), and 1 < e < f(n); mod is the modulo operation, that is, divide and take the remainder; p and q are a pair of different and large enough prime numbers; n is the modulus value; d is the private key exponent; f(n) is the Euler's totient function of n, f(p)=p - 1, f(q)=q - 1.

[0060] It should be noted that when encrypting, the plaintext is first transformed into an integer M from 0 to n-1; if the plaintext is long, it can be divided into appropriate groups before exchange; suppose A encrypts the message with B's public key and signs it with A's private key; after receiving the message, B first verifies the signature with A's public key, and then decrypts the message with his own private key after confirmation. Since the public key can be made public, the user only needs to keep his own private key, so the distribution of encryption keys will become very simple; at the same time, since each user's private key is unique, other users can not only verify the authenticity of the source of the information through the public key of the sender of the information, but also use digital signatures to ensure that the sender cannot deny having sent the information. Asymmetric encryption can prevent counterfeiting and denial, and is more suitable for confidential communication requirements in network communications.

[0061] Step 23: Transmit the encrypted information to a pre-built secure intelligent management platform for storage.

[0062] Step 3, using the pre-built security and intelligent management platform, perform threshold judgment on the user data to obtain positioning judgment results and vital sign index judgment results. Wherein, the pre-built security and intelligent management platform includes a decryption module, a storage module, a first threshold comparison module and a second threshold comparison module; the decryption module is used to decrypt the encrypted information using a pre-stored public key, obtain decrypted information, and extract user data from the decrypted information; the storage module is used to store the extracted user data; the first threshold comparison module is used to compare the location information in the user data with the preset location threshold to obtain the positioning judgment result; the second threshold comparison module is used to compare the vital sign index information in the user data with the preset index threshold to obtain the vital sign index judgment result.

[0063] Specifically, the process of performing threshold judgment on the user data to obtain the positioning judgment result and the vital sign index judgment result comprises the following steps:

[0064] Step 31: Decrypt the encrypted information using the public key pre-stored in the pre-built secure intelligent management platform to obtain decrypted information.

[0065] Step 32: extract user data from the decrypted information.

[0066] Step 33: Compare the location information in the user data with a preset location threshold to obtain a positioning judgment result.

[0067] Step 34: Compare the physical sign index information in the user data with the preset index threshold to obtain the physical sign index judgment result.

[0068] Step 4: Generate physical sign warning information or location warning information based on the positioning judgment result and the physical sign index judgment result, wherein the physical sign warning information or location warning information includes pop-up information, sound and light alarm information or short message.

[0069] In this embodiment 1, the location data and vital sign data of the child are collected through a smart bracelet. The child only needs to wear the smart bracelet to obtain dynamic heart rate, body temperature, blood pressure, sleep, and step counting health data, and upload the data to the child safety management smart platform. The information will be uploaded to the platform when the smart bracelet is worn or removed. When transmitting data, digital signatures and data encryption are used, and the SHA1withRSA algorithm is applied. The encrypted object is SHA1ed and then RSA encrypted, and the encrypted value is Base64 encoded to obtain the final key, which effectively ensures that the data will not be tampered with, ensures that the request is indeed sent by the key holder, and prevents data leakage. The sender can ensure the integrity and authenticity of the data during transmission, and the receiver can verify the integrity of the data and the identity of the sender.

[0070] The child safety management method described in this embodiment 1 is used to achieve safety management of children. Children can realize functions such as automatic positioning and vital signs monitoring by wearing smart bracelets, and can achieve real-time and accurate positioning through multiple positioning modules and cooperation with indoor positioning beacons; wherein, a network connection is established with the mobile operator through the built-in SIM card to send the child's information to the platform and analyze the data; during the data transmission process, the SHA1withRSA algorithm is used to encrypt the data to effectively ensure the accuracy and security of the data.
