In the embodiment of the invention, format verification comprises case verification, high similarity value verification and the like; each two-dimensional code can carry information of a provider, and whether the source of the two-dimensional code is normal or not can be judged by checking the information of the provider; the method also comprises trial-and-error checking, namely, whether the two-dimensional code is subjected to multiple trial-and-error or not is checked, and the checking can identify the two-dimensional code subjected to multiple trial-and-error by the current user or other users, so that the system or the user is reminded of possible risks of the two-dimensional code from the angle of the two-dimensional code. In addition, whether the two-dimension code is invalidated or not can be checked, and the user IP sending the access request through the invalidated or not activated two-dimension code can be prevented from being accessed or marked with an alarm.
In one embodiment, the security level comprises:
serious risk: the abnormal times of the gathering code scanning of the IP, the mobile phone number and the user ID reach the threshold preset by the system and request the IP address library in batches;
important risk: the code scanning times reach the system early warning value, invalid codes exist, trial-error codes exist, and the code scanning times reach the set threshold value in unit time;
abnormal risk: the method comprises the steps of regularly replacing IP addresses at high frequency to scan codes, requesting suspected machines in batches, and enabling a token with login failure to exist, wherein the user ID replacement frequency reaches a second-level threshold;
routine risk: the code scanning amount is increased suddenly in unit time, the trial-error IP/trial code reaches a set threshold, and the user ID replacement frequency reaches a first-level threshold;
normal state: no abnormal condition exists.
In the embodiment of the invention, for setting the threshold values, the range of the threshold values of different risk levels is different; for the same index, the higher the risk level, the greater the threshold. For users with serious risks, access is denied and the users are added to a blacklist; for users with important risks, access can be refused and added to the temporary blacklist, and the users are removed from the temporary blacklist when related early warning behaviors do not appear repeatedly in a period of time; access may be denied for the presence of abnormal risk; for the presence of conventional risks, access may be allowed, but the user is added to the supervision list to keep track of its subsequent operations; for normal state users, access may be allowed.
In one embodiment, the code scanning login early warning method further includes the following steps:
determining the proportion distribution of the user security level in the previous unit time;
and calling a level definition interface, and adjusting the item rule and the threshold according to the proportion distribution.
In the embodiment of the invention, the unit time can be determined according to the real-time flow of the user, for example, the flow standard is set to 1000 people, and the time length reaching 1000 people or the approximate value thereof is counted to be used as the unit time. In unit time, the number or proportion distribution of the security levels of the users is counted, when the high risk (including serious risk, important risk and abnormal risk for example) accounts for a certain value or the data reaches a certain value (for example, more than 50%), the system can judge that the current abnormal login requests are more, and the threshold value of each index can be temporarily reduced to prevent possible invasion, so that valuable login requests can be conveniently screened out from the login requests.
In one embodiment, the verification process further comprises the following steps after passing:
and returning to the level definition interface for the item end to call.
In the embodiment of the invention, it can be understood that after the login request of each user is processed, the definition interface is returned again, so that the real-time redefinition of each item can be realized.
