Verification method, system and device

Abstract

The invention provides a verification method comprising the following steps that: a server receives a verification request sent by a client side; the server generates a verification picture and a verification character group according to the verification request; the server sends the verification picture and the verification character group to the client side to ensure that the verification picture is displayed at the client side and the verification character group is displayed at a selected region of a display screen of the client side so as to be selected by a user; the server receives user input (which is acquired by the client side) in the selected region; and the server judges whether the client side passes the verification according to the user input in the selected region. The invention also provides a verification system, a server and a client side. Due to the adoption of a verification way that the user input is displayed for the user and received by the user through providing the verification picture and the verification character group, not only is the friendly level of the user in a verification process improved, but also the difficulty for program cracking verification is improved, and the verification effectiveness is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a verification method, system, server and client. Background technique [0002] In order to prevent malicious registration of accounts, etc., current websites often require users to input verification codes on some occasions. In the prior art, most of the verification codes use a character sequence of a-z, 0-9, and these characters are used to generate a picture, and then the user recognizes the picture and enters the corresponding character in the picture through the keyboard to complete the verification. However, for this verification technology, there is an automatic execution program that intelligently recognizes the characters in the picture to crack the verification. The existing technology only uses a small number of a-z, 0-9 characters. In order to increase the difficulty of cracking, the characters in the picture are usually extremely distorted, or noise pixels are...

However, for this verification technology, there is an automatic execution program that intelligently recognizes the characters in the picture to crack the verification

The existing technology only uses a small number of a-z, 0-9 characters. In order to increase the difficulty of cracking, the characters in the picture are usually extremely distorted, or noise pixels are added to the picture to make the background of the picture messy, but this method sometimes also Make it difficult for normal users to distinguish the verification code, which affects the use of normal users

Due to the limitation of the number of English words and the old interaction mode, it is difficult to increase the cost of cracking the verification code under the premise of ensuring that normal users can recognize it
