Access to and transmission of information is technically blocked through network blocking and authentication technologies.

In particular, in the case of government agencies or work where security is important, the performance of work through portable terminals is not activated due to the risk of data or information leakage.

Furthermore, the encryption and authentication technology described above cannot prevent data leakage by photographing the output screen of the portable terminal itself using another terminal, so there are technical limitations to information security.

Accordingly, the technology for digital watermarking, which displays the source or security level of digital content by implementing the security method of printing a watermark on printed matter in the past on a digital device, has been disclosed in Korean Patent Publication No. 10-2013-0039226, etc. It has been developed and provided.

However, such a watermark occupies a portion of the output content or is output overlapping on the content, so there is a problem of reducing the output range of the output content or reducing the readability of the output content.

In particular, in the case of portable terminals with relatively narrow output screens, there was a problem in that the screen utilization efficiency of the terminal was significantly reduced due to the output of the watermark.

Hereinafter, we will look at a secure mark output system for a portable terminal according to a specific embodiment of the present invention with reference to the attached drawings.

Figure 1 is a block diagram showing the configuration of the Secure Mark output system according to a specific embodiment of the present invention, Figure 2 is a flow chart showing the driving method of the Secure Mark output system according to a specific embodiment of the present invention, and Figure 3 is an exemplary diagram showing an example of a Secure Mark generated by the Secure Mark output system of the present invention, and Figure 4 is an exemplary diagram showing an example of operation of the Secure Mark output system according to a specific embodiment of the present invention.

First, as shown in Figure 1, the secure mark output system according to the present invention is provided in the portable terminal 100, and includes a detection unit 110, a recognition module 120, a sensor module 130, and a secure mark generation. It is configured to include a unit 140 and a secure mark output unit 150.

The detection unit 110 detects the operation of the portable terminal 100, and specifically determines whether the portable terminal 100 is running a specific web page or a specific application.

At this time, the detection target web pages and applications may be set by the user as web pages and applications that are subject to Secure Mark output that are determined to require security.

Meanwhile, the recognition module 120 collects user environment information indicating the use state of the portable terminal 100. Here, user environment information refers to the state of the person(s) located in front of the portable terminal. It speaks of information.

Accordingly, the recognition module 120 is for recognizing an object located in front of the portable terminal 100, and may be a front camera provided in the portable terminal 100 or a separately installed lidar sensor. .

This user environment information is used as a decision element by which the Secure Mark output unit 150, which will be described later, determines whether to output the Secure Mark.

And the sensor module 130 detects the rotation and movement state of the portable terminal 100, and may be composed of a gyro sensor provided in a smartphone.

Additionally, the sensor module 130 may be configured to include a GPS module provided in a smartphone, and thus it is also possible to acquire location information of the portable terminal 100.

Meanwhile, the secure mark generator 140 generates a secure mark to be output on the screen of the portable terminal 100.

At this time, as shown in FIG. 3, the secure mark is an image displaying a specific phrase requiring security, and the secure mark includes user information, terminal information, and visual information.

The user information is an identification mark indicating who the user currently using the web page or application is and can be obtained from login information on the application or web page.

And the terminal information is a unique code representing the wireless terminal, and can be obtained from information stored in the user terminal.

Additionally, the time information is information indicating the time of use of the web page and application and may be updated and changed according to changes in time.

In this way, since the user information, terminal information, and visual information are included in the Secure Mark, if content or web page information is leaked by voyeurism, etc., it is possible to determine the circumstances of the security data leak.

At this time, the secure mark may be implemented as a dynamic object (image). Preferably, the display direction, size, and ratio may be changed or the image may be moved according to a set cycle.

Of course, the output direction and size of the secure mark may change depending on the rotation of the portable terminal 100.

Furthermore, preferably, the secure mark is composed of two or more different colors and includes two different colors in a complementary color relationship. Accordingly, even if the color of the output screen is the same/similar to any color constituting the Secure Mark, the color portion in the complementary color relationship is clearly identified, allowing the user to easily identify the Secure Mark regardless of the color composition of the output screen.

Next, the Secure Mark output unit 150 determines whether the Secure Mark is output and outputs the Secure Mark. At this time, a method of determining whether the secure mark output unit 150 outputs the secure mark will be described in detail below.

Hereinafter, with reference to FIG. 2, the secure mark output method of the secure mark output system according to the present invention will be described in detail, focusing on the judgment method of the secure mark output unit 150.

As shown in Figure 2, the secure mark output method according to the present invention begins with the detection unit 110 detecting access to a specific application or web page (S110).

Thereafter, when the detection unit 110 detects that an application or web page requiring preset security is connected, the recognition module 120 recognizes the object in front and collects user environment information (S121), and the sensor The module 130 detects the rotation and movement state of the portable terminal 100 (S123), and the Secure Mark output unit 150 recognizes the driving state (recording/filming) of the terminal (S125).

And the Secure Mark output unit 150 is based on the user environment information collected in steps 121, 123, and 125, the rotation and movement state of the portable terminal 100, and the driving state (recording/filming) of the terminal. Accordingly, it is determined whether or not the Secure Mark is output, which will be explained in detail below.

Basically, in the present invention, when a user runs or views a security target application or web page (hereinafter referred to as a 'secure page'), the secure mark is not output when the user uses it alone, thereby causing inconvenience in use. It does not cause problems such as deterioration of readability, etc., but if others are viewing it or it is judged to be not in a normal usage environment, a secure mark is printed, thereby ensuring convenience of use and improving security.

To this end, the Secure Mark output unit 150 determines that the Secure Mark is output in the following situations.

First, when there are multiple observers viewing the secure page

To this end, the recognition module 120 recognizes objects in front of the portable terminal 100 and identifies a person's face through image analysis of the recognized objects.

At this time, since image analysis technology for objects is already a widely commercialized technology, detailed technical description will be omitted.

And if the number of recognized faces is multiple, the observer is identified among the faces. At this time, the observer refers to a face in a position where the actual secure page can be observed, and among all recognized faces, the distance from the terminal, the direction of the face, and the viewing range (angle) of the terminal screen are determined. It is judged.

To explain this using the example shown in FIG. 4, as shown, when the faces of five people (X1 to 5) are recognized in front of the portable terminal 100, the faces X4 are the separation distance (R) from the terminal. Because it exceeds the set value, it is excluded from observers.

In other words, it is desirable that the preset separation distance (R) is set to the maximum distance that allows an average person to read the mobile phone screen.

In addition, since the face X5 is outside the terminal viewing range (θ), it is also excluded from the observer.

In other words, it is desirable that the preset terminal viewing range (θ) is generally set by the maximum tilt angle at which the mobile phone screen can be read.

Next, face

Therefore, in the example shown in FIG. 4, only face X1 and face X2 are identified as observers.

Through this determination, when it is determined that there are a plurality of observers in front of the portable terminal 100, the secure mark output unit 150 outputs the secure mark.

Here, the Secure Mark output unit 150 can set the output form of the Secure Mark differently depending on the number of observers.

That is, the Secure Mark output unit 150 sets the dynamic change of the Secure Mark to be higher as the number of recognized observers increases, allowing the Secure Mark to move and change quickly.

Specifically, the greater the number of observers, the higher the risk of security page leakage, and in this case, the security page leakage is due to the observer's perspective. Therefore, the dynamic change of the Secure Mark can be increased as the risk of security page leakage increases, so that the readability of the security page can be variably reduced depending on the risk of security page leakage.

Second, when there is no observer viewing the secure page

As mentioned above, it is a high-risk situation when there are multiple observers who can observe the secure page, but the fact that the portable terminal 100 is outputting a secure page even though there are no observers is also an abnormal use situation, and a separate device is used. Therefore, there is a high risk that it may be a situation for taking pictures of the screen.

Accordingly, in the same manner as described above, the observer in front of the portable terminal 100 is identified, and if it is determined that there is no observer, the secure mark output unit 150 outputs a secure mark.

Third, when a photography means is recognized in front of the terminal that is printing a security page

In the same manner as described above, when a mobile phone or a camera is identified as a result of image analysis of objects in front of the portable terminal 100 recognized by the recognition module 120, the Secure Mark output unit 150 outputs the Secure Mark. Print out.

That is, as shown in the face

However, just because a mobile phone or camera is identified in front of the portable terminal 100, it does not mean that video recording of the security page is unconditionally performed. Therefore, the risk of filming a secure page by the recognized mobile phone or camera is determined by the dynamic movement of the recognized mobile phone or camera. (Movement amount) is judged based on the degree.

That is, in the present invention, when the mobile phone (or camera) located in front of the portable terminal 100 moves relatively much, the risk of voyeurism is judged to be low, while the risk of voyeurism is determined to be low when the mobile phone (or camera) located in front of the mobile terminal 100 moves relatively much. If there is little relative movement, the risk of voyeurism is judged to be high.

Here, the Secure Mark output unit 150 can set the output form of the Secure Mark differently depending on the risk of voyeurism by the mobile phone (or camera) in front.

That is, the Secure Mark output unit 150 determines that the smaller the dynamic movement amount is, the higher the risk of voyeurism is, according to the dynamic movement amount of the object recognized by the mobile phone (or camera), and lowers (darker) the transparency of the Secure Mark. It is determined that the greater the amount of dynamic movement, the lower the risk of voyeurism, and the transparency of the Secure Mark can be set high (more transparent) to ensure maximum user convenience.

Fourth, when there is no movement of the terminal that is printing the security page.

If there is no movement of the terminal that is outputting the security page, it means that the portable terminal 100 is mounted or left lying on a table.

In this case, the risk of voyeurism is also high, so the secure mark is printed.

To this end, the secure mark output unit 150 outputs the secure mark depending on whether the portable terminal 100 rotates or moves as detected by the sensor module 130.

Specifically, the secure mark output unit 150 outputs the secure mark when the rotation or movement of the portable terminal 100 is not detected by the sensor module 130 for more than a preset time.

Fifth, if the location of the terminal printing the security page is in an unauthorized area

In the present invention, a security vulnerable area and a security safe area can be distinguished, and a secure mark can be output when a user uses a secure page in a security vulnerable area.

For this purpose, the sensor module 130 may be configured to include a GPS sensor.

At this time, the Secure Mark output unit 150 outputs the Secure Mark if the user's location determined according to the received signal from the GPS sensor is a security vulnerable area.

Sixth, when the terminal that is printing the security page executes an unauthorized function.

Meanwhile, when the portable terminal 100 that is displaying a security page executes a specific function, there is a risk that security vulnerabilities may increase. At this time, the specific function may be video shooting, recording, or call function. Accordingly, the secure mark output unit 150 can output the secure mark when a video shooting, recording, or call function is being executed at the same time as the security page is output in the portable terminal.

Using the above-described determination method, the Secure Mark output unit 150 determines whether to output the Secure Mark, and when it is determined to output the Secure Mark, the Secure Mark generator 140 generates a Secure Mark (S140) ).

Afterwards, the secure mark output unit 150 outputs the generated secure mark (S150).

The rights of the present invention are not limited to the embodiments described above but are defined by the claims, and those skilled in the art can make various changes and modifications within the scope of the claims. This is self-evident.

The present invention is a secure mark output system for a portable terminal that detects the status of the user using the portable terminal and selectively outputs a secure mark with security information displayed when running a security-set application program through the portable terminal. Relatedly, according to the present invention, when running an application requiring security or accessing a web page through a portable terminal, a secure mark is printed on the output screen so that the user can pay attention to security management, thereby reducing security risks. This has the effect of allowing users to conveniently use portable terminals to perform security tasks and access security data.
