DETAILED DESCRIPTION

Below, a description will be given of examples of the disclosure with reference to the attached drawings. In this regard, the present disclosure may have different forms and should not be construed as being limited to the examples set forth herein.

An “image forming apparatus” may refer to any apparatus capable of performing an image forming job, such as a printer, a copier, a scanner, a fax machine, a multi-function printer (MFP), or a display device. Further, the image forming apparatus may be a two-dimensional (2D) image forming apparatus or a three-dimensional (3D) image forming apparatus. An “image forming job performed by the image forming apparatus” may refer to a job related to printing, copying, scanning, faxing, storing, sending, coating, etc., or a combination of two or more of the above jobs.

“Security setting information” may refer to information used to detect a security level for certain information. For example, the security setting information may include information about a security image or a security keyword used to detect a plurality of security levels. The security level may be classified according to the degree to which security is desired. For example, the higher the degree of security desired, the higher the security level.

“Security level information of a scanned document” may refer to information indicating a security level in which information included in a scanned document is detected according to security setting information. For example, the security level of the scanned document may be set for each page of the scanned document. For example, the security level of the scanned document may be set based on a result of detecting whether the information included in the scanned document is the same as or similar to at least one of a pre-registered security image and a security keyword.

“Security level information of a destination” may refer to information indicating a security level set to a user for a destination. For example, the security level may be set differently for each user. For example, based on user's security levels being different, the type or range of accessible information may be different. For example, the range of information accessible to a user set to a higher security level may be greater than the range of information accessible to a user set to a lower security level.

A “security document” may refer to a document generated from a scanned document based on a security level of a destination. For example, because different user's security levels have different types or ranges of accessible information, security documents generated from scanned documents for users with different security levels may be different from each other.

“Destination information” may refer to information about a destination used to transmit a certain document to a user. For example, the destination information may include at least one of scan-to-network, e-mail, scan-to-share, fax, scan-to-storage information, and the like.

Referring to FIG. 1, an image forming apparatus 10 may obtain information about a destination to which a document is to be received in operation 110. For example, the image forming apparatus 10 may obtain destination information for a plurality of users. For example, the image forming apparatus 10 may receive, through a user interface unit, information about a first destination for a first user, information about a second destination for a second user, information about a third destination for a third user, and so on.

In operation 120, the image forming apparatus 10 may generate a security document according to a security level for each destination. For example, the range of information that can be disclosed may be different for each of the plurality of users. For example, based on the plurality of users having different work scopes or different work rights, information provided for the same document may be set differently. Accordingly, the image forming apparatus 10 may generate a security document corresponding to each security level of the plurality of users for each destination of the plurality of users.

For example, it may be assumed that a document is composed of three pages, and security levels are classified into level 1, level 2, and level 3, wherein level 1 has a higher security level than level 2 and level 2 has a higher security level than level 3. That is, the closer to level 1, the higher the security level, and the range of accessible information may also be greater than the range of accessible information according to the lower security level. In addition, it is assumed that the security level of the first user is level 1, the security level of the second user is level 2, and the security level of the third user is level 3.

For example, pages of a document accessible to a user with a security level of level 1 may be pages 1, 2, and 3. In addition, pages of a document accessible to a user with a security level of level 2 may be pages 1 and 2. In addition, pages of a document accessible to a user with a security level of level 3 may be pages 1 and 3. The image forming apparatus 10 may generate a security document corresponding to a user's security level. For example, the image forming apparatus 10 may generate a first security document composed of page 1, page 2, and page 3, a second security document composed of page 1 and page 2, and a third security document composed of page 1 and page 3.

In operation 130, the image forming apparatus 10 may transmit the security documents to respective destinations. For example, the image forming apparatus 10 may transmit the first security document according to the information of the first destination, transmit the second security document according to the information of the second destination, and transmit the third security document according to the information of the third destination.

FIG. 4 is a view for explaining a security level and security information about the security level according to an example.

Referring to FIG. 4, the image forming apparatus 10 may provide information differently according to a security level of a destination. Because a work scope or work authority may be different for each user, information accessible to each user may be managed differently. For example, a security level may be classified according to a work scope or work authority. For example, the security level may be classified into five levels as shown in FIG. 4. For example, the security level may be classified into level 1, level 2, level 3, level 4, and level 5. For example, the closer to level 1, the more information that requires security, and the closer to level 5, the greater the range of information that can be disclosed or the range of users that can be disclosed.

For example, level 1 may be a level with the highest security level. For example, security information having a security level of level 1 may be personal information such as a personal phone number, a resident number, a company number, a personal profile, and the like. For example, the security information of which the security level is level 1 may be information that can be shared with a personnel manager.

For example, security information of which the security level is level 2 may be plan information such as a business plan, a project, a new product, a competitor trend, and the like. For example, the security information of which the security level is level 2 may be information that can be shared with a marketing department or the like.

For example, the security information of which the security level is level 3 may be information that can be shared with a strategic planning department, an in-house executive, and the like.

For example, security information of which the security level is level 4 may be security information included in a document in which phrases such as confidential, security, confidentiality, and the like are written. For example, the security information of which the security level is level 4 may be information that can be shared with in-house employees.

For example, security information of which the security level is level 5 may be information that can be shared with an external user.

In FIG. 4, the security level is classified into five levels, but the security level may be classified into more or fewer than five levels.

In addition, the image forming apparatus 10 may register a security image or a security keyword corresponding to each security level. For example, the image forming apparatus 10 may compare information included in a scanned document with a security image or a security keyword. In other words, the image forming apparatus 10 may detect a security level of a scanned document based on a result of detecting whether information included in the scanned document is the same as or similar to a security image or a security keyword.

For example, based on personal information such as personal phone number, resident registration number, company number, personal profile, etc. being detected in the scanned document, the image forming apparatus 10 may detect the security level of the scanned document as level 1. As an example, the image forming apparatus 10 may read the scanned document and detect whether a security image or a security keyword corresponding to personal information is included in the scanned document. Based on the resident registration number being detected in the scanned document, the image forming apparatus 10 may detect the security level of the scanned document as level 1.

FIG. 5 is a view for explaining a screen for setting a user's destination and a user's security level according to an example.

For example, the image forming apparatus 10 may provide an e-mail item 510 and a fax item 520 indicating items of a user's destination. The image forming apparatus 10 may receive information about at least one of the e-mail item 510 and the fax item 520 for a user. For example, the image forming apparatus 10 may provide at least one of a scan-to-network item, a scan-to-share item, a scan-to-storage item, and the like.

For example, the image forming apparatus 10 may display a security level item 530 for setting a user's security level. For example, the user's security level may be set by an input of an administrator. In addition, the user's security level may be set based on at least one of a user's work scope or a user's work authority previously stored in the image forming apparatus 10.

For example, the image forming apparatus 10 may display at least one icon from among an icon for adding a user's address information, an icon for editing the user's address information, and an icon for deleting the user's address information.

FIGS. 6A to 6C are views for explaining a screen for setting a security level of a scanned document according to an example.

The image forming apparatus 10 may obtain security level information for each page of a scanned document. Because information included for each page of the scanned document may be different, the security level may be different for each page of the scanned document. The image forming apparatus 10 may display security level information detected for each page of the scanned document. The image forming apparatus 10 may receive an input for finally setting a security level for each page of the scanned document. The image forming apparatus 10 may obtain security level information of the scanned document based on an input for finally setting a security level for each page of the scanned document.

Referring to FIG. 6A, the image forming apparatus 10 may display information 611 of pages constituting the scanned document. For example, the image forming apparatus 10 may receive an input for selecting a second page 612 from among pages of the scanned document. The image forming apparatus 10 may display security level information 613 of the second page 612. For example, a security level of the second page 612 may be level 2.

For example, a first security policy may include a policy capable of providing information of a certain page to a user of a higher security level including a security level of the certain page. For example, because the security level of the second page 612 is level 2, providing information of the second page 612 to a user with a security level of level 1 and a user with a security level of level 2 may satisfy the criteria of the first security policy.

For example, the image forming apparatus 10 may display a user interface 614 for setting a security level within a higher security level range including the security level of the second page 612. For example, the image forming apparatus 10 may display the user interface 614 in which levels 1 and 2 are selectable and level 3, level 4, and level 5 are not selectable based on the first security policy. For example, in the user interface 614, icons corresponding to levels 1 and 2 may be displayed in an active state, and icons corresponding to levels 3, 4, and 5 may be displayed in an inactive state. For example, the image forming apparatus 10 may receive an input for selecting levels 1 and 2 through the user interface 614. The image forming apparatus 10 may detect a transmittable security level for the second page 612 as levels 1 and 2. In other words, the image forming apparatus 10 may detect that the second page 612 may be transmitted to users with security levels of levels 1 and 2.

Referring to FIG. 6B, the image forming apparatus 10 may display information 621 of pages constituting a scanned document. For example, the image forming apparatus 10 may receive an input for selecting a sixth page 622 from among pages of the scanned document. The image forming apparatus 10 may display security level information 623 of the sixth page 622. For example, a security level of the sixth page 622 may be level 5.

For example, the first security policy may include a policy capable of providing information of a certain page to a user of a higher security level including a security level of the certain page. For example, because the security level of the sixth page 622 is level 5, it may be allowed to provide information of the sixth page 622 to users with security levels of levels 1, 2, 3, 4, and 5.

For example, the image forming apparatus 10 may display a user interface 624 for setting a security level within a higher security level range including the security level of the sixth page 622. For example, the image forming apparatus 10 may display the user interface 624 for selecting levels 1, 2, 3, 4, and 5 based on the first security policy. For example, the image forming apparatus 10 may receive an input for selecting levels 1, 3, and 4 through the user interface 624. The image forming apparatus 10 may detect a transmittable security level for the sixth page 622 as levels 1, 3, and 4. In other words, the image forming apparatus 10 may detect that the sixth page 622 may be transmitted to users with security levels of levels 1, 3, and 4.

In FIGS. 6A and 6B, an example process of setting a security level of a page of a scanned document based on the first security policy capable of providing information of a certain page to a user of a higher security level including a security level of the certain page has been described. However, referring to FIG. 6C, a process of setting a security level of a page of a scanned document based on a second security policy in which information about a certain page is not limited by a security level of the certain page will be described. For example, based on the second security policy being activated, the first security policy may be inactivated.

For example, the image forming apparatus 10 may control the second security policy to be activated based on an input for selecting the second security policy from among the security policies. Referring to FIG. 6C, the image forming apparatus 10 may display the information 611 of pages constituting a scanned document. For example, the image forming apparatus 10 may receive an input for selecting the second page 612 from among pages of the scanned document. The image forming apparatus 10 may display the security level information 613 of the second page 612. Although a security level of the second page 612 is level 2, the image forming apparatus 10 may display a user interface 631 capable of selecting levels 1 and 2, and also levels 3, 4, and 5 that are lower than level 2.

For example, the image forming apparatus 10 may receive an input for selecting levels 1 and 4 through the user interface 631. The image forming apparatus 10 may detect a transmittable security level for the second page 612 as levels 1 and 4. In other words, the image forming apparatus 10 may detect that the second page 612 may be transmitted to users with security levels of levels 1 and 4.

FIG. 7 is a view for explaining a security document generated for each of a plurality of security levels according to an example.

In an example, the image forming apparatus 10 may generate security documents respectively corresponding to security levels of a plurality of destinations for respective security levels of the plurality of destinations based on a result of comparing security level information of a scanned document to security level information of the plurality of destinations. For example, the image forming apparatus 10 may generate a security document composed of pages that are allowed according to the security level information of the plurality of destinations from among pages of the scanned document.

For example, a document may be composed of 7 pages. A scanned document obtained by scanning a document may also be composed of 7 pages. A security level finally set for a second page of the scanned document may be level 1 and level 2, as described with reference to FIG. 6A. In addition, a security level finally set for a sixth page of the scanned document may be levels 1, 3, and 4, as described with reference to FIG. 6B. Security levels finally set for first page, third page, fourth page, fifth page, and seventh page of the scanned document may be level 1 to level 5.

Referring to FIG. 7, a security document 710 that can be transmitted to a user with a security level of level 1 may be composed of first to seventh pages. A security document 720 that can be transmitted to a user with a security level of level 2 may be composed of first to fifth and seventh pages. A security document 730 that can be transmitted to a user with a security level of level 3 may be composed of first and third to seventh pages. A security document 740 that can be transmitted to a user with a security level of level 4 may be composed of first and third to seventh pages. A security document 750 that can be transmitted to a user with a security level of level 5 may be composed of first, third to fifth, and seventh pages.

Accordingly, a user may receive a security document to which a security of a document is applied according to a user's security level.

FIG. 8 is a view for explaining a security level set for each of a plurality of users according to an example.

In an example, because each user has a different work scope or work authority, the type and content of accessible information may be set differently for each user. For example, the image forming apparatus 10 may transmit a security document to which security is applied according to a security level of a destination based on performing a document transmission job. For example, the security level may be classified into level 1 to level 5 according to a user's work scope or a user's work authority. In the illustrated example, the user's security level may be set to a certain level from among five levels.

Referring to FIG. 8, a security level of a first user and a fifth user may be set to level 1, a security level of a second user and a fourth user may be set to level 2, a security level of a sixth user may be set to level 3, a security level of a third user and a seventh user may be set to level 4, and a security level of an eighth user to a tenth user may be set to level 5.

FIG. 9 is a view for explaining destination information of a plurality of users according to an example.

In an example, the image forming apparatus 10 may receive information about at least one destination for a user through a user interface unit. For example, as described in FIG. 5, the image forming apparatus 10 may receive, through a user interface unit, information about a user's name, a user's e-mail, a user's fax, and a user's security level. The image forming apparatus 10 may store at least one destination information for a user.

Referring to FIG. 9, the destination information may include at least one of scan-to-network, e-mail, scan-to-share, fax, and scan-to-storage information. For example, the image forming apparatus 10 may store destination information for an e-mail and a fax of a first user, store destination information for a scan-to-network, an e-mail, and a fax of a second user, store destination information for a scan-to-share and a scan-to-storage of a third user, store destination information for an e-mail of a fourth user, and store destination information for an e-mail and a fax of a fifth user. In addition, the image forming apparatus 10 may store destination information for a scan-to-network of a sixth user, store destination information for a scan-to-network and a scan-to-share of a seventh user, store destination information for an e-mail and a fax of an eighth user, store destination information for a scan-to-share of a ninth user, and store destination information for an e-mail of a tenth user.

The image forming apparatus 10 may transmit a security document to at least one destination selected from among user destinations.

FIG. 10 is a view for explaining a receiving destination according to a security level and job type of a scanned document according to an example.

In an example, the image forming apparatus 10 may generate a security document corresponding to a security level of each destination for each destination. For example, as described in FIG. 7, the image forming apparatus 10 may generate a security document 710 that can be transmitted to a user with a security level of level 1, a security document 720 that can be transmitted to a user with a security level of level 2, a security document 730 that can be transmitted to a user with a security level of level 3, a security document 740 that can be transmitted to a user with a security level of level 4, and a security document 750 that can be transmitted to a user with a security level of level 5.

Referring to FIG. 10, the image forming apparatus 10 may store a receiving destination according to a security level and a job type. For example, as described in FIGS. 8 and 9, the image forming apparatus 10, based on information about a security level and destination set for each of a plurality of users, may store destination information according to the security level and job type.

For example, the image forming apparatus 10 may transmit a security document to a first user and a fifth user with a security level of level 1 based on destination information of an e-mail or fax.

FIG. 11 is a flowchart illustrating an operating method of components of an image forming apparatus according to an example.
