BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 shows one sample of display not showing the ID or the password on the terminal for remotely instructing work.

DESCRIPTION OF EMBODIMENTS

Embodiments of the present invention will be described below. However, this is illustrative only, and the technological scope of the present invention is not limited thereto.

The system for remotely supporting work of the present invention displays the image on a terminal for remotely instructing work after processed to make an ID or a password invisible when the image shared between a user terminal and the terminal for remotely instructing work contains an ID or a password. The user is one who receives a remote work instruction from a remote work instructor who remotely instructs work. The user terminal is at least provided with an imaging unit such as a camera. The image may be a moving image and a still image.

A preferable embodiment of the present invention will be described below with reference to FIG. 1. FIG. 1 shows one sample of display not showing the ID or the password on the terminal for remotely instructing work according to a preferable embodiment of the present invention.

The system for remotely supporting work includes a detection unit, a processing unit, a display unit, and a receiving unit that the control unit achieves by reading a predetermined program. These units may be of an application type, a cloud type, or the like. The above-mentioned units may each be achieved by a single computer or two or more computers (e.g., a server and a terminal).

The detection unit detects an ID or a password contained in the image when an image taken by a user terminal is shared between the user terminal and a terminal for remotely instructing work to remotely support work. To detect an ID or a password contained in the image, optical character recognition (hereinafter referred to as “OCR”) may be used. Alternatively, the IDs or passwords detected in the past may be mechanically learned as teacher data to detect an ID or a password contained in the image. The machine learning improves the accuracy of detection.

The processing unit processes the image to make the ID or the password invisible if an ID or a password is detected. For example, the processing means tessellating, blackening, or masking the image with a stamp.

The processing unit may specify the position displaying the ID or the password contained in the image and may process only the part of the image that corresponds to the position to make the ID or the password invisible, if an ID or a password is detected. Specifically, since only the part of the ID or the password is made invisible but the other parts are visible, it is easier to remotely instruct work than if the entire image is made invisible. Furthermore, since the parts other than the ID or the password are visible, the situation can be known to remotely instruct work easily. For example, only the part of the ID or the password is made invisible as shown in FIG. 1. The character string “ID” or “password” may also be made invisible at the same time.

Alternatively, the processing unit may not specify the position displaying the ID or the password contained in the image and may process the entire image to make the ID or the password invisible, if an ID or a password is detected. In this case, since the entire image is invisible, the security can be more tightened than the case where only the part of the ID or the password is invisible, even if the processing partly fails. Furthermore, even if the position of the ID or the password is failed to be specified, the leak of information is prevented because the entire image is invisible.

The display unit displays the processed image on the terminal for remotely instructing work. The display unit may display that the image has been processed. This enables a remote work instructor who uses the terminal for remotely instructing work to recognize that the displayed image has been processed. As the result, the remote work instructor easily remotely instructs work. Furthermore, if the aspect ratio of the screen of the user terminal is different from that of the terminal for remotely instructing work as shown in FIG. 1, the image may be displayed on the terminal for remotely instructing work to maintain the aspect ratio of the image taken by the user terminal (for example, by displaying the part enclosed with a broken line on the terminal for remotely instructing work as shown in FIG. 1).

The receiving unit receives a remote work instruction for the displayed processed image from the terminal for remotely instructing work. The remote work instructor can input a remote work instruction for the user from the terminal for remotely instructing work to the user terminal. The remote work instruction is necessary for work from a remote place, for example, by drawing and displaying a red circle in the image to tell the machine to be operated, by displaying a cubic arrow icon to tell the correct imaging direction, or appropriately changing and displaying to tell the progress of work.

The receiving unit receives a remote work instruction for the part other than that processed to make the ID or the password invisible in the displayed processed image but does not receive a remote work instruction for the part processed to make the ID or the password invisible. This prevents the problem in which for example, the ID or the password is remotely instructed to be made visible from occurring. In other words, the security is tightened by not interfering in the part processed to make the ID or the password invisible.

The detection unit detects the character string “ID” or “password” contained in the image, and then the processing unit processes the image to make the characters around the character string invisible if an ID or a password is detected. Generally, in the management of IDs or passwords, a determined ID or password is often shown on the left, right, top, or bottom of the character string “ID” or “password.” Based on this, the ID or the password is invisible as shown in FIG. 1 by processing the image to make the characters around the character string “ID” or “password” invisible. The character string “ID” or “password” may also be made invisible at the same time. This enables a remote work instructor to hardly guess that the invisible part contains an ID or a password.

Process Behavior

The method for remotely supporting work will be described below. The method for remotely supporting work displays the image on a terminal for remotely instructing work after processed to make an ID and a password invisible when the image shared between a user terminal and the terminal for remotely instructing work contains an ID and a password.

The method for supporting remote at least includes a detection step, a processing step, a display step, and a receiving step.

In the detection step, the above-mentioned detection unit detects an ID or a password contained in the image when an image taken by a user terminal is shared between the user terminal and a terminal for remotely instructing work to remotely support work. To detect an ID or a password contained in the image, OCR may be used. Alternatively, the IDs or passwords detected in the past may be mechanically learned as teacher data to detect an ID or a password contained in the image. The accuracy of detection improves by the machine learning.

In the processing step, the above-mentioned processing unit processes the image to make the ID and the password invisible if an ID or a password is detected. For example, the processing means tessellating, blackening, or masking the image with a stamp.

In the processing step, the above-mentioned processing unit may specify the position displaying the ID or the password contained in the image and may process only the part of the image that corresponds to the position to make the ID or the password invisible, if an ID or a password is detected (masking). Specifically, since only the part of the ID or the password is made invisible but the other parts are visible, it is easier to remotely instruct work than if the entire image is made invisible. Furthermore, since the parts other than the ID or the password are visible, the situation can be known to remotely instruct work easily. For example, only the part of the ID or the password is made invisible as shown in FIG. 1. The character string “ID” or “password” may also be made invisible at the same time.

Alternatively, in the processing step, the above-mentioned processing unit may not specify the position displaying the ID or the password contained in the image and may process the entire image to make the ID or the password invisible, if an ID or a password is detected (masking). In this case, since the entire image is invisible, the security can be more tightened than the case where only the part of the ID or the password is invisible, even if the processing partly fails. Furthermore, even if the position of the ID or the password is failed to be specified, the leak of information is prevented because the entire image is invisible.

In the display step, the above-mentioned display unit displays the processed image on the terminal for remotely instructing work. The display unit may display that the image has been processed. This enables a remote work instructor who uses the terminal for remotely instructing work to recognize that the displayed image has been processed. As the result, the remote work instructor easily instructs remote work. Furthermore, if the aspect ratio of the screen of the user terminal is different from that of the terminal for remotely instructing work as shown in FIG. 1, the image may be displayed on the terminal for remotely instructing work to maintain the aspect ratio of the image taken by the user terminal (for example, by displaying the part enclosed with a broken line on the terminal for remotely instructing work as shown in FIG. 1).

In the receiving step, the above-mentioned receiving unit receives a remote work instruction for the displayed processed image from the terminal for remotely instructing work. The remote work instructor can input a remote work instruction for the user from the terminal for remotely instructing work to the user terminal. The remote work instruction is necessary for work from a remote place, for example, by drawing and displaying a red circle in the image to tell the machine to be operated, by displaying a cubic arrow icon to tell the correct imaging direction, or appropriately changing and displaying to tell the progress of work.

In the receiving step, the above-mentioned receiving unit receives a remote work instruction for the part other than that processed to make the ID or the password invisible in the displayed processed image but does not receive a remote work instruction for the part processed to make the ID or the password invisible. This prevents the problem in which for example, the ID or the password is remotely instructed to be made visible from occurring. In other words, the security is tightened by not interfering in the part processed to make the ID or the password invisible.

In the detection step, the above-mentioned detection unit detects the character string “ID” or “password” contained in the image, and then the processing unit processes the image to make the characters around the character string invisible if an ID or a password is detected. Generally, in the management of IDs or passwords, a determined ID or password is often shown on the left, right, top, or bottom of the character string “ID” or “password.” Based on this, the ID or the password is invisible as shown in FIG. 1 by processing the image to make the characters around the character string “ID” or “password” invisible. The character string “ID” or “password” may also be made invisible at the same time. This enables a remote work instructor to hardly guess that the invisible part contains an ID or a password.

To achieve the means and the functions that are described above, a computer (including a CPU, an information processor, and various terminals) reads and executes a predetermined program. For example, the program may be an application installed in a computer, may be provided through Software as a Service (SaaS), specifically, from a computer through a network, or may be provided in the form recorded in a computer-readable medium such as a flexible disk, CD (e.g., CD-ROM), or DVD (e.g., DVD-ROM, DVD-RAM). In this case, a computer reads a program from the record medium, forwards and stores the program to and in an internal or an external storage, and executes it. The program may be previously recorded in, for example, a storage (record medium) such as a magnetic disk, an optical disk, or a magnetic optical disk and provided from the storage to a computer through a communication line.

As the specific algorithm of the above-mentioned machine learning, the nearest neighbor algorithm, the naive Bayes algorithm, the decision tree, and the support vector machine, etc. may be used.
