Abstract: A user attribute matching method and a terminal are provided. The method may include generating, by a first terminal, a key by using an ElGamal algorithm, and encrypting a first user attribute value vector of the first terminal by using the public key, to form a first ciphertext. The method may also include sending the first ciphertext and the public key to a second terminal, receiving a second ciphertext and a third ciphertext that are sent by the second terminal, and decrypting the received second ciphertext and third ciphertext based on the private key. The method may also include obtaining a matching similarity between user attributes of the first terminal and the second terminal based on the decrypted second ciphertext and third ciphertext. In the method matching, efficiency is improved, and operation load of a terminal is relieved.
