All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected unless otherwise explicitly stated or limited. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
Example one
The present embodiment provides an information leakage prevention method, which is particularly suitable for data information protection of an intelligent terminal device having a network communication function, and along with the multi-functionalization and intelligentization of the terminal device, an address book, a photo, important business data, and the like are stored in the terminal device, so how to ensure information security in the terminal device is a technical problem mainly solved by the present embodiment, as shown in fig. 1, the information leakage prevention method includes:
judging whether to start a loss mode;
when the loss mode is started, shielding an input signal for controlling the shutdown of the terminal equipment 1 and shielding an input signal for controlling the disconnection of the network connection of the terminal equipment 1, and controlling the action of a card lock mechanism to lock the SIM card and/or the memory card.
According to the information leakage prevention method, by setting the loss mode, when the loss mode is started, some functions of the terminal equipment can be locked from the aspect of software control, malicious shutdown, checking or copying of data information in the terminal equipment by people can be prevented, so that processing time can be strived for a loser, an input signal for disconnecting network connection can be shielded through software control, the network which loses the terminal equipment is kept smooth, and a user can control data transfer and deletion control of the lost terminal equipment through the network. Meanwhile, in terms of hardware, the SIM card and/or the memory card storing data materials are mechanically locked, and data loss caused by reading after the card is forcibly taken out by a person is prevented. The scheme can guarantee the data security of the terminal equipment in all directions.
The control logic of the lost mode should be embedded in the system, and the lost mode can be turned on by operating the terminal device or by network control of other terminal devices (hereinafter referred to as external devices).
When the lost mode is started through the external equipment network control, the external equipment is provided with the application software which is the same as that of the lost terminal equipment, and a user logs in the local application software by using the external equipment and the account which is the same as that of the lost terminal equipment. And operating the external equipment to establish network connection with the lost terminal equipment to realize remote control of the lost terminal equipment.
As shown in fig. 2, the preferred method for starting the lost mode in this embodiment is:
the external device sends a loss notification to the terminal device through the communication network 2;
and after receiving the loss notification, the terminal equipment starts a loss mode.
In order to prevent the terminal device from being powered off, which may cause the external device to fail to communicate with the terminal device and thus fail to perform a series of protection controls, after the loss mode is turned on, some functions are disabled locally by the lost terminal device.
At present, there are two shutdown modes of terminal equipment, one is to input a shutdown control signal to control shutdown by operating an external key, and the other is to control shutdown by operating a touch screen and software. Therefore, after the loss mode is started, the input signal for controlling the shutdown of the screen of the terminal equipment can be shielded, including shielding the shutdown input signal from the key and shielding the shutdown input signal from the touch screen, so as to keep the terminal equipment in a startup state.
The terminal device can shield some functions, and also can keep some functions, for example, a function of answering a call can be kept, so that a user can conveniently find out other people who contact the terminal device through phone contact.
In order to prevent the terminal device from being disconnected from the network, which causes the external device to be unable to keep communicating with the lost terminal device, and further to be difficult to copy or delete data in the terminal device, after the loss mode is started, the method also comprises the step of shielding an input signal for controlling the terminal device to disconnect the network connection so as to keep the network smooth, and a user can copy important data in time during the period, so that the loss caused by the loss of the important data is avoided.
The external device may copy the data stored in the terminal device through the communication network, and the copied data may be stored in the network server or in the external device.
Before controlling the card locking mechanism to act, the method also comprises the step of detecting the current card locking mechanism state, and when the card locking mechanism does not lock the SIM card and/or the storage card, the card locking mechanism is controlled to act to lock the SIM card and/or the storage card. If the card-locking mechanism is in a state of locking the SIM card and/or the memory card, there is no need to control the action thereof.
In order to further ensure the security of the user data and at the same time frighten others to attempt to illegally occupy the terminal device and steal data, in this embodiment, it is preferable that the method further includes controlling the terminal device to be forcibly set to the ring mode when the loss mode is turned on. And the mode of shielding the key input signal and shielding the touch screen input signal can also be used for preventing the ring mode from being closed again.
In order to help the user to quickly retrieve the lost terminal equipment, when the lost mode is started, the terminal equipment also acquires the position information of the lost terminal equipment and sends the position information to the external equipment. The user can help the terminal equipment to find the terminal equipment by positioning the position of the terminal equipment.
In order to further secure the user profile and prevent the terminal device from being disassembled violently, and the SIM card and/or the memory card still have the risk of data leakage when being taken out, it is preferable that the terminal device also deletes and destroys the data stored in the terminal device when the loss mode starts. The controlling step may be arranged to be completed after the user copies the data.
The method aims to solve the problem that a user cannot find that the terminal equipment is lost at the first time, so that the lost mode cannot be controlled to be started in time, and the lost mode cannot be started when the terminal equipment is powered off at the moment. The user can still send the loss notice to the terminal equipment through the external equipment, and when the terminal equipment is started again, the loss notice is automatically received, and the loss mode is controlled to be started. So as to maximally secure the data and reduce the user loss. After the loss mode is started, the terminal device immediately executes a series of control of the loss mode, thereby preventing the terminal device from being forcibly powered off again or closing the network.
