Description

TECHNICAL FIELD [Method and apparatus for processing personal information protection]

The present invention relates to a method and apparatus for protecting user-friendly personal information.

As problems such as illegal leakage, misuse, and collection of personal information have increased due to the recent expansion of information and communication networks, awareness of the importance of personal information has increased very much. Therefore, the Personal Information Protection Act has been enacted for the purpose of eradicating the leakage and abuse of personal information in numerous countries at home and abroad. According to the Personal Information Protection Act, encryption of unstructured data included in copies of various identification cards, contracts, and applications in databases such as financial institutions is required.

Various encryption technologies are being developed to protect information transmitted through the network, but documents or photos containing personal information in public institutions, banks, companies, hospitals, etc., for example, copies of ID cards, contracts, applications, hospital records, etc. There is no processing to protect the personal information contained. In addition, personal information is leaked through offline documents such as printouts, faxes, and invoices from courier boxes, and information protection processing for these documents is required.

Until now, in order to protect personal information in documents and photos, personal information is manually non-visualized, but if it is non-visualized by hand, it cannot be restored to the original personal information and reused later. It has this impossible problem.

In a situation where the distribution of data containing sensitive personal information through social media or the Internet is becoming active, there is a need for a technology that enables users to more easily protect personal information.

The problem to be solved by the present invention is to provide a method and apparatus for protecting personal information that can effectively protect personal information.

Personal information protection processing method according to a feature of the present invention, the step of obtaining an image including personal information; Recognizing personal information from the image; Non-visualizing the recognized personal information; And generating and outputting an image including the non-visualized personal information.

According to an embodiment of the present invention, only personal information is automatically non-visualized in documents or materials including personal information, thereby preventing personal information from being exposed. In addition, for an image including non-visualized personal information, non-visualized personal information may be visualized so that it can be confirmed. In the case of distributing or using documents or videos that contain personal information, only sensitive personal information can be masked and covered, thus providing effective countermeasures to prevent personal information from being leaked.

In addition, the user can easily cover only major personal information by non-visual processing, and if it is necessary to legally check the non-visual personal information later, it can be visualized again in real time so that the personal information can be confirmed.

However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and similar reference numerals are attached to similar parts throughout the specification.

Throughout the specification, when a certain part "includes" a certain component, it means that other components may be further included rather than excluding other components unless specifically stated to the contrary.

Hereinafter, a method and apparatus for protecting personal information according to an embodiment of the present invention will be described.

1 is a diagram showing the concept of personal information protection processing according to an embodiment of the present invention.

In an embodiment of the present invention, an image including personal information is acquired from a device such as a camera or a scanner, or an image including personal information input in the form of a digital file is acquired, and personal information is recognized from the acquired image, and the recognition Non-visualized personal information is processed, and an image including non-visualized personal information is output in the form of a digital file or a hard copy output.

Images including personal information according to an embodiment of the present invention are physical media such as ID cards, passports, credit cards, business cards, hospital records, documents, documents such as courier boxes or mailing invoices, photos, CCTV, black boxes, etc. It includes images obtained from various types of objects on which personal information is recorded, such as photographs of (eg, car numbers, etc.), digital files (eg, JPEG files, MPEG files, Munsun files, etc.). In addition, in an embodiment of the present invention, personal information includes all information to be protected.

2 is a flowchart of a method for protecting personal information according to an embodiment of the present invention.

In an embodiment of the present invention, an image including personal information is acquired as shown in FIGS. 1 and 2 (S100). For example, an object on which personal information such as a document, an ID card, a credit card, or a photo is recorded is photographed using a photographing device such as a camera to obtain an image of the object, that is, an image including personal information. For example, an image including personal information may be obtained by photographing a document including personal information submitted to a financial sector or a telecommunication company using a camera of a mobile phone. Alternatively, an image including such personal information may be input in the form of a digital image file.

In this way, in a state in which an image including personal information is acquired, personal information is recognized from the image (S110). For example, based on edge information, shape information, color distribution information, etc. for the image, personal information may be recognized in an image, or a preset area for an image may be recognized as an image corresponding to the personal information. A method of recognizing personal information in an image may use a known image recognition technology, and the present invention is not limited to this method of recognizing personal information.

Personal information is recognized from the image, and the recognized personal information is non-visualized (S120). For example, masking in which personal information is de-visualized by simply covering other images such as a black square, or masking in which personal information is encrypted and invisible is possible. When the recognized personal information is encrypted using an encryption key, personal information can be masked from blurry to completely random image types depending on the encryption strength, and the original personal information is re-visualized using the same encryption key later. can do. If there is no need for a visualization process to restore the original personal information, a method of simply covering the personal information with another image, such as a black square, can be used as a masking technique.

Thereafter, an image including non-visualized personal information is generated (S130). In response to the image acquired in step S100, an image in which only personal information is non-visualized by masking is generated.

In this way, the processed image is output (S140). Specifically, an image including non-visualized personal information may be stored in the form of a digital file or transmitted to another device through a network, or may be output in the form of a hard copy document, or may be displayed through a display device. have.

On the other hand, if an object containing personal information (document, identification card, credit card, photo, etc.) is manually photographed with a camera such as a smartphone and is to be processed for non-visualization, the image corresponding to the personal information is immediately It can be acquired and non-visualized. Specifically, if the camera position is adjusted to accurately match the area where personal information exists, that is, the image obtained from the camera by adjusting the focus position of the camera on the object is an image corresponding to the area where personal information exists (e.g. For example, if it is an image of a square area in which the resident number is recorded in the application or the like), non-visualization processing is performed on the area of the acquired personal information.

In this case, unlike the process of capturing an image and extracting an area where personal information exists by performing a separate extraction process from the captured image, when an image of an area where personal information exists is acquired during image capturing, it is immediately compared. By performing visualization processing, faster non-visualization processing of personal information can be performed.

In the personal information protection processing method according to the embodiment of the present invention described above, the entire process may be displayed so that the user can visually check it.

Next, as described above, a method of restoring personal information from an image including non-visualized personal information will be described.

3 is a diagram illustrating a concept of restoring personal information when masking is performed using an encryption technique in an embodiment of the present invention.

In an embodiment of the present invention, non-visualized personal information is selectively extracted and recognized from a digital file containing non-visualized personal information or an image acquired from an output, and then visualized, and an image containing the original personal information. Restore.

4 is a flowchart of a process of restoring information in a method for protecting personal information according to an embodiment of the present invention.

In an embodiment of the present invention, specifically, as shown in FIGS. 3 and 4, an image including non-visualized personal information is acquired (S300). Specifically, a document including non-visualized personal information, an object such as an ID card, a credit card, or a photograph is photographed using a photographing device such as a camera, and an image including non-visualized personal information is obtained. For example, an image including non-visualized personal information is obtained from a hardcopy document that is processed and output according to the above-described personal information protection processing method. In addition, an image in the form of a digital file including non-visualized personal information may be input. For example, from a digital file including non-visualized personal information transmitted through a network or a digital file including non-visualized personal information input through an input interface, an image including non-visualized personal information is Can be obtained.

In this way, in a state in which an image including non-visualized personal information is acquired, non-visualized personal information is recognized from the image (S310).

Then, the recognized non-visualized personal information is visualized (S320). For example, non-visualized personal information may be unmasked by using a decryption key corresponding to an encryption key used for non-visualization of personal information. Original personal information can be obtained by unmasking the personal information masked in a blurry form.

Thereafter, the image including the original personal information is restored using the unmasked personal information (S330). By applying the unmasked personal information to the image obtained in step 300, an image including the original personal information is generated.

In this way, the reconstructed image is output (S340). Specifically, an image including visualized personal information may be stored in the form of a digital file or transmitted to another device through a network, or may be output in the form of a hard copy document, or may be displayed through a display device. .

In the information restoration process according to the embodiment of the present invention described above, the entire process may be displayed so that the user can visually check the entire process.

On the other hand, if you want to visualize personal information by photographing an object containing non-visualized personal information with a camera such as a smart phone, when an image is acquired from the object, an image corresponding to the non-visualized personal information is immediately acquired and visualized. I can. Specifically, when the camera position is adjusted to accurately match the area where personal information exists, that is, the image obtained from the camera by adjusting the focus position of the camera on the object corresponds to the area in which non-visual personal information exists. In this case, visualization processing is performed on the area of the acquired personal information. In particular, in the case of manually photographing non-visual personal information by the method of FIG. 1 described above, the visualization process may not be performed unless accurate position alignment is performed. For example, if the object has an area of non-visualized personal information in a square shape, only when a positional alignment is made in which the captured image becomes an image of a shape that matches the area of the non-visualized personal information in the rectangular shape. Visualization processing can be performed. Accordingly, non-visualized personal information can be prevented from being easily visualized to some extent.

Non-visualization processing and visualization processing according to an embodiment of the present invention correspond to visualization by non-visualization and decryption processing by a cryptographic method based on cryptographic theory, respectively, if only encryption key information used in the encryption process is shared. Visualization processing can be performed easily and automatically. The masking embodiment in which personal information is simply covered with an image such as black without using an encryption method can be used when non-visualization is not required.

The embodiments of the present invention as described above can be used to protect personal information in various fields.

Specifically, only personal information such as a resident registration number is automatically non-visualized and stored as a file through the user photographing an ID card with a mobile phone, thereby preventing an accident in which personal information is exposed. This method can be applied to an identification card or documents submitted to a financial sector, a telecommunications company, or a hospital record document, so that an accident in which personal information is exposed can be prevented.

In addition, personal information such as a car number of an image acquired through a CCTV or a black box is non-visualized and stored as a file, thereby preventing personal information from being exposed through the image.

In addition, since only personal information such as an address or a mobile phone number can be non-visualized and output in the form of a printout, this can be applied to, for example, a delivery box or a waybill of a mail to prevent personal information from being exposed. In this case, it is possible to provide a security service in which personal information such as a name or address written on the waybill of a courier or mail can be non-visualized, and only a smartphone of a courier or postal delivery person can check non-visual personal information.

In addition, as described above, even if a video file containing non-visualized personal information is leaked to the outside, an authorized user can visualize and check personal information only on a specific device, thus preventing the leakage of personal information at the source. can do.

In addition, when a user submits documents or data including his/her personal information to financial institutions, public institutions, or telecommunications companies, by applying the personal information protection processing method according to the embodiment of the present invention, only personal information is non-visualized. Upon submission, only the person in charge checks the personal information on the display using the cryptographic key shared by the person in charge of the institution, and the submitted data is stored in a non-visualized state and documents are processed to prevent leakage of personal information. can do.

In addition, in addition to personal information, after distributing the data to the customer by non-visualizing the information that the operator wants to hide, the customer can automatically view the hidden information when shooting with his or her smartphone or opening a video file. The embodiments of the present invention can be utilized in business fields such as lottery tickets and online cultural gift certificates.
