Detailed ways

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

An embodiment of the present invention provides a data encryption transmission method. The method in the embodiment of the present invention is applied to a smart terminal. As shown in FIG. 1 , it is a flowchart of a data encryption transmission method according to an embodiment of the present invention. The specific steps of the method of the embodiment of the present invention are as follows:

Step S101: Preset the key of the light-based visible light wireless communication corresponding to the data to be transmitted.

Wherein, the secret key includes at least one of the following: the color of the light, the flickering frequency of the light, and the intensity of the light. For example, the key could just be the color of the light. The key can also include the color of the light, the frequency at which the light blinks, and the intensity of the light. Since the color of the light can obtain a huge number of color types (255×255×255 kinds) by setting the ratio of the three primary colors of red, green and blue, the possibility of malicious data transmission is greatly reduced. If combined with setting the flickering frequency and/or the intensity of the light, this method controls whether to transmit data at the source of the data extremely strictly, and ensures that the data is not transmitted maliciously at the source of the data.

The color of the above-mentioned light, the flickering frequency of the light, and the intensity of the light can all be set by the user according to their own needs. Preferably, since the power consumption of the RGB three primary colors is red, green and blue in descending order, considering the importance of power consumption to the smart terminal, the color of the light used as the secret key is preferentially selected as red. Specifically, the color of the light can be obtained by detecting the wave length of the light with a spectrophotometer. The flickering frequency of the light and the intensity of the light can be obtained through the detection of the photosensitive sensor.

Step S102: Obtain the secret key of the visible light wireless communication based on the emitted light of the smart terminal.

Specifically, depending on the type of the key, the color of the emitted light can be obtained by detecting the wave length of the light with a spectrophotometer, and the flicker frequency and intensity of the emitted light can be obtained through detection by a photosensitive sensor.

Step S103: matching the secret key of the emitted light with the secret key of the preset light corresponding to the data to be transmitted.

If the matching is successful, go to step S104; otherwise, go to step S105.

Step S104: Transmitting the data to be transmitted based on visible light wireless communication by emitting light.

Visible light wireless communication (called LiFi--Light Fidelity) uses fast light pulses to transmit data wirelessly. The principle is to encode data in light according to different rates. For example, LED on means 1, and off means 0. These binary data can be quickly encoded into light signals, and data can be effectively transmitted through fast switches.

Step S105: Emitting light does not transmit the data to be transmitted.

The method of the embodiment of the present invention uses the LiFi method to transmit data, so that the secret key of the light corresponding to the data to be transmitted can be set, and whether the light emitted is determined by whether the secret key of the emitted light successfully matches the key of the light corresponding to the data to be transmitted Data can be transmitted, ensuring that the data to be transmitted is not easy to be deciphered, greatly reducing the possibility of malicious transmission of data, and greatly reducing the possibility of interception of transmitted data, making data transmission simpler and safer.

Another embodiment of the present invention also provides a data encryption transmission method. In addition to including the above-mentioned steps, the method of this another embodiment preferably also includes before step S101:

Based on the selection of data to be transmitted by the smart terminal user, the data to be transmitted is set to be transmitted based on visible light wireless communication.

There are several ways to transfer data. In order to make data transmission more secure, smart terminal users can set important data to be transmitted based on visible light wireless communication. Specifically, the LiFi signal source can be set to emit light. For example, the light emitted by the LiFi signal source may be light emitted by a flashlight, light from a screen, and the like.

Preferably, before step S102, the method in this other embodiment further includes: setting a secret key for emitting light.

The key for emitting light may also include at least one of the following: the color of the light, the flickering frequency of the light, and the intensity of the light. For example, the key to emitting light could simply be the color of the light. The key for emitting light may also include the color of the light, the flickering frequency of the light and the intensity of the light at the same time.

The secret key for emitting light can be set by the user of the smart terminal. Only by setting the secret key of the emitted light can the secret key of the emitted light be matched with the secret key of the corresponding light to be transmitted.

Preferably, the method of another embodiment of the present invention also includes:

If the number of times that the secret key of the emitted light does not match the secret key of the preset light corresponding to the data to be transmitted reaches the preset limited number of times, the data to be transmitted is hidden.

The preset limited number of times is set by the smart terminal user according to specific needs. For example, for generally important data, the preset limit times may be 5 times; for very important data, the preset limit times may be 3 times. It should be understood that the limited number of times is not limited to this, and may also be other times.

Through the above steps, the data to be transmitted can be hidden after the number of mismatches between the secret key of the emitted light and the secret key of the corresponding light corresponding to the preset data to be transmitted reaches the limit number of times, so as to prevent the data to be transmitted from being maliciously transmitted possibility.

Preferably, the method in another embodiment hides the data to be transmitted in at least one of the following ways:

(1) Create a hidden folder in the external storage of the smart terminal, and move the data to be transferred to the hidden folder.

If you name a folder starting with a dot "." in the external storage, the folder is a hidden folder. Therefore, the folder created in this way can hide data.

(2) Create a folder in the internal storage of the smart terminal, and move the data to be transferred into the folder.

The internal storage of the smart terminal is an area that the user of the smart terminal cannot access (such as the data directory of the smart phone). Therefore, if a folder is created in the internal storage of the smart terminal, the folder can hide data.

When the data is moved to the internal storage that cannot be accessed by the user, its security is the highest, and the data will not be deleted. Therefore, the preferred way to hide the data is to create a folder in the internal storage of the smart terminal and move the data to the file in the middle.

To sum up, the data encryption transmission method in another embodiment of the present invention uses the LiFi method to transmit data, so that the secret key corresponding to the light to be transmitted can be set, and whether the secret key of the emitted light and the secret key of the corresponding light to be transmitted Successful matching is used to determine whether the emitted light can transmit the data to be transmitted. When the number of times that the secret key of the emitted light does not match the secret key of the corresponding light of the preset data to be transmitted reaches the preset limit, the data to be transmitted can be transmitted Data hiding ensures that data is not easy to be deciphered, greatly reduces the possibility of malicious data transmission, and also greatly reduces the possibility of data transmission being intercepted, making data transmission simpler and safer.

For example, the key could just be the color of the light. The key can also include the color of the light, the frequency at which the light blinks, and the intensity of the light. Among them, because the color of the light can obtain a huge number of color types (255×255×255 kinds) by setting the ratio of the three primary colors of red, green and blue, thus greatly reducing the possibility of data being maliciously transmitted. If combined with setting the flicker frequency and intensity of the light, this method controls whether to transmit data at the source of the data extremely strictly, and ensures that the data is not transmitted maliciously at the source of the data.

The color of the above-mentioned light, the flickering frequency of the light, and the intensity of the light can all be set by the user according to their own needs. Preferably, since the power consumption of the RGB three primary colors is red, green and blue in descending order, considering the importance of power consumption to the smart terminal, the color of the light used as the secret key is preferentially selected as red. Specifically, the color of the light can be obtained by detecting the wave length of the light with a spectrophotometer. The flickering frequency of the light and the intensity of the light can be obtained through the detection of the photosensitive sensor.

The secret key matching module 203 is configured to match the secret key of the emitted light with the secret key of the corresponding light preset for the data to be transmitted.

The data transmission module 204 is configured to transmit light to transmit the data to be transmitted based on visible light wireless communication if the matching is successful; otherwise, transmit light not to transmit the data to be transmitted.

Visible light wireless communication (called LiFi--Light Fidelity) uses fast light pulses to transmit data wirelessly. The principle is to encode data in light according to different rates. For example, LED on means 1, and off means 0. These binary data can be quickly encoded into light signals, and data can be effectively transmitted through fast switches.

The smart terminal of the embodiment of the present invention uses the LiFi method to transmit data, so that the secret key of the light corresponding to the data to be transmitted can be set, and the emitted light is determined by whether the secret key of the emitted light matches the secret key of the corresponding light of the data to be transmitted successfully. Whether the data to be transmitted can be transmitted ensures that the data is not easy to be deciphered, greatly reduces the possibility of malicious transmission of data, and also greatly reduces the possibility of interception of transmitted data, making data transmission simpler and safer.

There are several ways to transfer data. In order to make data transmission more secure, smart terminal users can set important data to be transmitted based on visible light wireless communication. Specifically, the LiFi signal source can be set to emit light. For example, the light emitted by the LiFi signal source may be light emitted by a flashlight, light from a screen, and the like.

Preferably, the intelligent terminal of this another embodiment also includes:

The key for emitting light may also include at least one of the following: the color of the light, the flickering frequency of the light, and the intensity of the light. For example, the key to emitting light could simply be the color of the light. The key for emitting light may also include the color of the light, the flickering frequency of the light and the intensity of the light at the same time.

For example, for generally important data, the preset limit times may be 5 times; for very important data, the preset limit times may be 3 times. It should be understood that the limited number of times is not limited to this, and may also be other times.

Through the above-mentioned module design, after the number of mismatches between the key for emitting light and the key for the corresponding light that is preset to transmit data reaches the limit, the data can be hidden to avoid the possibility of data being maliciously transmitted.

More preferably, the data hiding module 207 includes at least one of the following submodules:

The first data hiding sub-module 2071 is configured to create a hidden folder in the external storage of the smart terminal, and move the data to be transmitted to the hidden folder.
