Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 1 shows a flowchart of a method for defending against security of an electronic device provided in this embodiment, including:
s101, acquiring a plurality of user head portraits in the using process of the electronic equipment.
The electronic equipment is equipment which can store and check data and is provided with a camera, such as a computer and a mobile phone.
The user head portrait is the head portrait of the current user automatically acquired by a camera in the electronic equipment in the process of using the electronic equipment by the user.
Specifically, when a user opens the electronic device for use, a camera of the electronic device can acquire a plurality of user head portraits in the use process of the electronic device in real time or according to a preset period, so as to be used for determining a target user subsequently.
The method comprises the steps of acquiring information safety of the electronic equipment in real time, and acquiring the information safety according to a preset period, wherein the information safety of the electronic equipment can be guaranteed in time, and the storage space of the electronic equipment can be greatly saved on the premise of guaranteeing the equipment safety.
S102, if the fact that the plurality of user head portraits are head portraits of a first user is judged, the first user is determined to be a target user.
The first user is a user corresponding to a plurality of user head portraits acquired in the using process of the electronic equipment.
The target user is a user who uses the electronic device for a long time, namely, an owner of the electronic device.
It should be noted that the target user may be a plurality of users, for example, the number of users of the home computer is often 2-3.
S103, acquiring an avatar of a second user in the using process of the electronic equipment, and executing security defense operation if the second user is judged to be not the target user according to the avatar of the second user.
The second user is the user who uses the electronic equipment each time after the target user is determined.
For example, fig. 2 is a schematic diagram illustrating the results of security defense of electronic devices by using Windows users as an example, wherein the upper half area of fig. 2 is the registered target users, including hooked "wangjian" and unhooked "fangpeixin", and the lower half area of fig. 2 is the head portrait collection record of the illegal user, and fig. 2 currently shows several head portraits of 6 illegal users.
The security defense operation is a defense operation performed to prevent information leakage of the electronic device.
The security defense operation can be to store the head portrait of the second user and lock the electronic device, so that the information of the illegal user can be recorded, and the electronic device can be locked to ensure the information security.
The security defense operation may further be to send the avatar of the second user and the security prompt information to a target terminal, and determine whether to lock the electronic device according to feedback information sent by the target terminal. The target terminal can be a mobile phone of a target user, and timely informs the target user of possible embezzlement risks of the electronic equipment by timely feeding back an illegal user to the target terminal of the target user, and meanwhile, unnecessary misunderstandings can be avoided, for example, an owner of the computer gives other people to use the computer.
According to the embodiment, the target user is determined by automatically acquiring the head portrait of the user, and the security defense operation is executed by judging that the acquired head portrait of the second user is not the head portrait of the target user, so that the user does not need to set a password or acquire characteristic information such as fingerprints in advance, the information security of the electronic equipment can be ensured, and the complicated unlocking operation can be avoided.
Further, on the basis of the above method embodiment, S102 specifically includes:
s1021, if the fact that the user head portraits in the target time period are the head portraits of the first user is judged and known, setting the safety coefficient of the first user as a safety coefficient value corresponding to the target time period according to the time coefficient corresponding table;
s1022, if the safety coefficient value is larger than the threshold value, determining the first user as a target user.
The target time periods are a plurality of preset time periods and are used for gradually determining the target users. For example, if the target time period is 3 days, the corresponding safety factor value is 1.0; if the target time period is 7 days, the corresponding safety coefficient value is 2.0; if the target time period is 15 days, the corresponding safety coefficient value is 3.0; if the target time period is greater than 15 days, the corresponding safety factor value is 5.0.
The time coefficient corresponding table is a corresponding table of a target time period and a safety coefficient value, for example, if the time period is more than or equal to 3 days and less than 7 days, the corresponding safety coefficient value is 1.0; if the number of days is more than or equal to 7 and less than 15 days, the corresponding safety coefficient value is 3.0; greater than 15 days, the corresponding safety factor value is 5.0.
The safety factor represents a parameter whether each user is safe.
The safety coefficient value is the value of the safety coefficient corresponding to each user.
Specifically, through the front camera of the electronic equipment such as mobile phone equipment and a notebook computer, in the operation of the electronic equipment, the user can capture a facial head portrait at a certain time interval, background analysis and comparison are performed, and the head portrait of a target user which may be the owner of the equipment is screened out finally.
For example, when the user uses the electronic equipment every day, the background captures the facial head image of the user once every 10 minutes for feature analysis; the confirmed head portrait is a primary user coefficient of 1.0 in the analysis process of 3 days of use, the confirmed head portrait is a middle-level user coefficient of 2.0 in the analysis process of 7 days of use, the confirmed head portrait is a high-level user coefficient of 3.0 in the analysis process of 15 days of use, and the analysis process of more than 15 days of use is a long-term user. The electronic equipment monitors whether a user is the user in the whole using process, and if the user is not the user, the user can take a picture and keep the picture and lock the equipment.
The electronic equipment security defense method provided by the embodiment is compatible with the technology or equipment manufacturer needing to use Windows underlying driver, and has the capability of independently developing and improving the operating system. Aiming at the safety supplementary protection of new electronic equipment without any password and basic protection, the intelligent matching equipment user is achieved through algorithm and face recognition, the real owner of the equipment is recognized, the purpose of protecting the equipment safety of the user even if the user does not set the password after buying a mobile phone is achieved, and when the equipment is stolen and lost, the data safety and the equipment are protected from being stolen.
In the embodiment, through data accumulation screening and matching calculation, the user who uses the equipment most frequently is automatically set as a default user (target user) to give a security access right, and other users need to be authorized by the default user, so that the basic security defense measures are ensured when the password is not set by the default of electronic equipment such as a Windows operating system computer, an Andorid mobile phone and the like.
