The invention discloses a method and equipment for generating random numbers based on biological characteristics, and a medium. The method comprises the following steps: collecting multiple groups of biological characteristic data of a user; combining the multiple groups of biological characteristic data to obtain a biological characteristic value corresponding to the user; carrying out Hash on the biological characteristic value to obtain a first Hash value; and combining the first hash value with the current timestamp, performing hash, generating a second hash value, and taking the second hash value as a random number. The biological characteristics of each user are different, so that the random number is generated based on the biological characteristics, the randomness of the random number can be effectively ensured, the random number is difficult to crack, and the information security of the user is ensured. Generally, existing equipment, especially intelligent mobile equipment such as an intelligent mobi
