Described are a signature verification method, apparatus, and system. The method includes: encrypting a third-party payment identifier and payment information according to a first key to obtain a first signature; encrypting a third-party client identifier and first signature information according to a second key to obtain a second signature; and providing the third-party client identifier, the first signature information, and the second signature to a client server for verification, thereby solving a problem in the background that both a third-party merchant and a payment service party have a key of the third-party merchant used in a payment information transmission process, and once the key is leaked, other people can tamper with or forge order information by using the key, which easily causes property losses to a user or the third-party merchant and has low security, and achieving an effect of improving verification accuracy and improving security of payment information by verifying two signatures. |
