Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a configuration diagram illustrating a system for providing a file aging service in accordance with an embodiment of the present invention. Referring to FIG. 1, a system for providing a file aging service 1 may include a user terminal 100, a file aging service providing server 300 and a content upload server 400. The system for providing a file aging service 1 illustrated in FIG. 1 is for illustrative purpose only of an embodiment of the present invention, and does not in any way limit the present invention to FIG. 1.
The components in FIG. 1 are generally connected one another through a network 200. For example, as illustrated in FIG. 1, the user terminal 100 and file aging service server 300 may be connected each other through the network 200. Further, the file aging service server 300 may be connected to the content upload server 400 through the network 200. The user terminal 100 may be connected to the content upload server 400 by way of the file aging service server 300.
Here, the network 200 means a connection topology capable of exchanging information between respective nodes such as terminals and servers, which may include Internet, LAN (Local Area Network), Wireless LAN, WAN (Wide Area Network), PAN (Personal Area Network), 3G, 4G, LTE, and Wi-Fi but is not limited thereto. Further, it is understood that the user terminal 100, the file aging service server 300 and the content upload server 400 disclosed in FIG. 1 are not limited to those illustrated in FIG. 1.
The user terminal 100 may be a terminal that uploads or transmits contents to websites, applications, messengers, and clouds, PCs, or E-mails. Specifically, the user terminal 100 may identify content uploaded or transmitted from a site that is hosted by the file aging service server 300. Further, the user terminal 100 may identify an extinction time of the content uploaded through the file aging service server 300. The user terminal 100 may also delete the uploaded content, delay or advance the extinction time of the content, or restore the content again. The user terminal 100 may be implemented by a terminal that may connect to servers or terminals at a remote location through the network 200. The user terminal 100 may be implemented by a computer that may connect to servers or terminals at a remote location through the network 200. Here, the computer may include, for example, a notebook computer, desktop computer, laptop computer or the like having a camera mounted therein. Further, the user terminal 100 may be implemented by a terminal that may connect to servers or terminals at a remote location through the network 200. The user terminal 100 may be a wireless communication device that ensures portability and mobility, for example, which may include any kind of handheld-based wireless communication device such as a handset for PCS (Personal Communication System), GSM (Global System for Mobile communication), PDC (Personal Digital Cellular), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access) and Wibro (Wireless Broadband Internet), Smartphone, Smartpad, Tablet PC, or the like.
The file aging service server 300 may be a server that receives a content upload event from the user terminal 100 through the content upload server 400, and maps to the user terminal 100 an extinction time of the content contained in the content upload event to store a mapped result. By doing so, the file aging service server 300 may map the content uploaded by the user terminal 100 and websites, applications, messengers, clouds, PCs and E-mail servers in which the uploaded content is located. Further, when the extinction time of the content comes near, the file aging service server 300 may inform the user terminal of the extinction time of the content by transmitting an extinction notice message of the content to the user terminal 100. In this regard, upon receiving an extinction rejuvenation message of the content from the user terminal 100 in response to the extinction notice message, the file aging service server 300 may output a de-aging signal of the content. In the meantime, upon receiving an extinction confirmation message of the content from the user terminal 100, the file aging service server 300 may transmit a content extinction signal to at least one site or the content upload server 400 to allow the deletion of the relevant content. Accordingly, the file aging service server 300 may enable a user of the user terminal 100 to identify in one site as to whether what content which site or terminal stores. Furthermore, the file aging service server 300 may allow the user to set a lifecycle of contents, and identify whether a lifecycle-expired content should be deleted to thereby decrease junk data on website and protect personal literacy works. The file aging service server 300 may be implemented by a computer device that may connect to server or terminals at a remote location through the network 200. Here, the computer device may include, for example a notebook computer, desktop computer, laptop computer or the like having a camera mounted therein.
The content upload server 400 may be at least one of a messenger service server, social network service server, Internet service server, text message service server, cloud service server and mail service server. The content upload server 400 may be a server that connects to the user terminal 100 and uploads or stores the content. Particularly, the content upload server 400 may transmit the de-aging signal or content extinction signal to the file aging service server 300. Accordingly, the content upload server 400 enables the content not to be deleted when it receives the de-aging signal, and enables the content to be deleted when it receives the content extinction signal. The content upload server 400 may be implemented by a computer device that may connect to servers or terminals at a remote location through the network 200. The content upload server 400 may be implemented by a terminal that may connect to servers or terminals at a remote location through the network 200.
FIG. 2 is a block diagram illustrating the file aging service server illustrated in FIG. 1, and FIGS. 3A to 3G are diagrams illustrating an embodiment in which a file aging service served through FIG. 1 is driven in a website and a user terminal.
Referring to FIG. 2, the file aging service server 300 may include a receiving unit 310, a storage 320, a transforming unit 330, a transmitting unit 340, an aging unit 350, an automatic processing unit 360, and a time changing unit 370.
When the file aging service server 300 or another server (not shown) that interworks with the file aging service server 300 transmits to the user terminal 100 or the content upload server 400 an application, program or web page for providing a file aging service, the user terminal 100 or the content upload server 400 may install or open the application, program or web page for the file aging service. Further, a file aging service program may be driven in the user terminal 100 or the content upload server 400 using scripts implemented in a web browser. Here, the web browser refers to a program that enables a web (WWW: World wide web) service to be used, which means a program that receives and shows a hypertext scripted in HTML (Hyper Text Mark-up Language), and may include Netscape, Explorer and Chrome, for example. Further, the application means an application program on a terminal, for example, including an application program (app.) executed on a mobile terminal (smart phone). The app. may be installed by downloading it from a mobile application market being a virtual market where mobile contents are freely dealt in.
In addition, the connection to the network 200 means an interconnection among the terminal 100, the file aging service server 300, and the content upload server 400 that are in communication with one another. Further, the establishment of the connection to the network 200 means that the file aging service server 300 generates a communication object at a communication connection point in order to communicate with terminals which are connected through the network 200. The file aging service server 300 may exchange data one another through the communication object.
The receiving unit 310 may receive the content upload event from the user terminal 100 through the content upload server 400. The content upload event may include as meta information an identification number of the user terminal 100, ID and password information of the user terminal 100, URL information having a reference to an uploaded content, and information about the extinction time of the content indicating when the uploaded content become extinct. For example, the ID and password information of the user terminal 100 may include ID and password of a site where the contents are present. In addition, the ID and password information may also include ID and password of a site that is hosted by the file aging service server 300. In order to discriminate between them, the ID and password may be tagged with a tag or meta information, identifying to which site or application they belong.
The storage 320 may store a mapping of the extinction time of the content included in the content upload event to the user terminal 100. In this connection, the storage 320 may post the content uploaded by the user terminal and the extinction time of the content on the site which is hosted by the file aging service server 300. As illustrated in FIG. 3A, for example, the content and the extinction time of the content may be overlay-displayed on a user interface as follows: (1) when there exist files or texts uploaded by the user terminal 100 on a social network, portal site or other sites, (2) on the site hosted by the file aging service server 300, (3) when files or texts are listed up and displayed, (4) on a user interface which allows the restoration of the content according to an answer message from the user terminal 100, and (5) on a user interface which allows the deletion of contents according to a extinction time of the contents. At this time, (1) a timer used to set the extinction time of the contents through the user terminal 100 may be provided in a social network, portal site or other sites. Further, (2) the site hosted by the file aging service server 300 may provide a service to integrally check content of the user terminal 100 distributed in each site, and an environment to manage a lifecycle of the content. Further, (3) the user of the user terminal 100 may identify an aging process of the contents according to the content's lifecycle set by the user using a user interface. Furthermore, (4) the site hosted by the file aging service server 300 may provide an environment in which a user of the user terminal 100 can change, store or restore a extinction time of the content uploaded by the user, and (5) a site hosted by the file aging service server 300 may manage the content by informing the user terminal 100 that an extinction time of the content comes near.
Referring to FIG. 2 again, the transforming unit 330 may output the aging signal of the content based on a time difference between the extinction time of the content and a current time to transform the content. For example, a transformation degree of the content may correspond to the time difference between the extinction time of the content and the current time. At this time, the aging signal for the content may be transmitted to at least one site and the content upload server 400. Further, the aging signal for the content may be one to control at least one of fading, scratching, noise and transparency with respect to a user interface to display the content. For example, the content upload server 400 may be at least one of a messenger service server, a social network service server, an Internet service server, a text message service server, a cloud service server and a mail service server. Further, the content upload server 400 may provide the user terminal 100 with a user interface corresponding to a timer that may be used to set the extinction time of content when the content is uploaded by the user terminal 100. Furthermore, the content upload server 400 may transform the content in accordance with the aging signal.
The transmission unit 340 may transmit the extinction notice message of the content to the user terminal 100 within a preset time period from an extinction time of the content. At this time, the file aging service server 300 may provide at least one site to display content uploaded to the content upload server 400 and the extinction time of the content. The aging unit 350 may receive an answer message to the extinction notice message of the content from the user terminal 100. In case where the answer message is an extinction rejuvenation message of the content, the aging unit 350 outputs a de-aging signal of the content. In case where the answer message is an extinction confirmation message of the content, the aging unit 350 transmits an extinction message of the content to at least one site and the content upload server 400 so that the content can be deleted. As used herein, the de-aging signal of the content may be any of an extinction time changing signal of the content that allows delaying the extinction time of the content, a content storage signal that allows storing the content in the user terminal 100 or the content upload server 400, or an extinction time resetting signal that allows resetting the extinction time of the content. At this time, the content upload server 400 and the file aging service server 300 may implement a synchronization of the contents uploaded at the extinction time.
The automatic processing unit 360 may receive from the user terminal 100 an ID and password for accessing the content upload server 400 by the user terminal 100 via the content upload server 400, or directly receive the ID and password of the user terminal 400 from the content upload server 400. Further, the automatic processing unit 360 may map the received ID and password to the user terminal 100 and the content upload server 400 which is accessed by the ID and password to store a mapped result. When receiving an answer message in response to the extinction notice message of the content from the user terminal 100, the automatic processing unit 360 outputs a de-aging signal of the content if the answer message is the extinction rejuvenation message; and outputs the extinction signal of the content if the answer message is the extinction confirmation message. In this regard, the automatic processing unit 360 may search a site hosted by the content upload server 400 for a user interface used to input ID and password, for example, using an image identification algorithm. As an example, the automatic processing unit 360 may extract coordinate values of the user interface to input the ID and password from the site hosted by the content upload server 400 and coordinate values corresponding to a screen size and a screen magnification of the user terminal 100, thereby searching the user interface. For example, when it is assumed that an arbitrary site is searched for, coordinate values of a box (a user interface) to input the ID and password may be extracted by scanning the site in the form of an image and reading texts of the scanned image. Here, a method may be used to extract a box type template using an image template and read coordinates of a corresponding template. In this case, since the coordinate values may be changed due to diversity of screen sizes and screen magnifications of the user terminal 100, the coordinate values may be changed to adapt to various kinds of screen sizes and screen magnifications. Thereafter, the automatic processing unit 360 may restore the extinction state by inputting the received ID and password into the searched user interface used to input the ID and password and make de-aging of the content uploaded by the user terminal 100, otherwise automatically extinct the content uploaded by the user terminal 100.
The timing changing unit 370 may receive a search event for the content uploaded by the user terminal 100 from the content upload server 400, and change the extinction time of the content based on the received search event. At this time, the extinction time of the content becomes delayed as the number of searches included in the search event becomes increased, and the extinction time of the content becomes advanced as the number of searches included in the search event becomes decreased. That is, it may be possible to accelerate aging of the content when the content is required by nobody or of no value, utilizing the database efficiently.
Herein below, by way of an example, an embodiment that a file aging service is driven on a messenger-based server will be described with reference to FIG. 3B.
For example, when a text is uploaded by the user terminal 100 as illustrated in FIG. 3B, an extinction time of text may be set by the user terminal, and the file aging service server 300 may allow the text to be deleted ({circle around (3)} marked in FIG. 3B) so as not to be seen when the extinction time of the text expires. Further, the file aging service server 300 may preset a time to a chat room ({circle around (2)} marked in FIG. 3B) in which a plurality of user terminals 100 participates so that the chat room may be remained only for the preset time. Further, even when chat rooms among the user terminals 100 are listed up, the extinction times ({circle around (1)} marked in FIG. 3C) of the chat room may be displayed as illustrated in FIG. 3C. Furthermore, an aging progress of an image may be displayed using a user interface element as the extinction time of the image comes near as illustrated in FIG. 3D. Also, the image may be automatically deleted when an effective lifecycle expires. Additionally, in case where an extinction time is set for chat and shared contents registered by the user terminal 100 in the chat room, it may be possible to design that the user terminal 100, which has set the extinction time, controls operations such as copy and download of the content.
In summary, the file aging service server 300 may receive a chat participation event from a plurality of user terminals 100. Then, the file aging service server 300 may receive a content upload event from a user terminal 100 among the plurality of user terminals 100 and transmit the content included in the content upload event to the plurality of user terminals 100. The file aging service server 300 may count a time difference between the extinction time of the content included in the content upload event and a current time and transmit the counted time difference to the plurality of user terminals 100. At this time, when the extinction time of the content is identical to the current time, the file aging service server 300 may transmit the extinction time to the user terminals 100 so that the content can be deleted. In this case, the plurality of user terminals 100 may display the received and counted time difference in the form of a text, an image or a video. For example, the text may view to count a residual time, the image may view as a timer image and the video may view as a residual time that is counted while being overlaid on the timer image. Here, the file aging service server 300 may output the aging signal for the content to the plurality of user terminals 100 based on the time difference between the extinction time of the content and the current time to transform the content. The aging signal for the content may be a signal to control at least one of fading, scratching, noise and transparency of a user interface which displays the content.
An embodiment that a file aging service is driven on a PC (Personal Computer)-based server will be described with reference to FIGS. 3E to 3G.
Referring to FIG. 3E, the file aging service server 300 may detect a storage event to operate a timer when a program is installed or a file is stored in a PC, and a user of the PC may set an extinction time of the program or file ({circle around (1)} marked in FIG. 3E). Further, as the extinction time of the program or file comes near, the file aging service server 300 may provide an aging progress of the content using a user interface element. The file aging service server 300 may delete the installed program or file when it reaches the extinction time ({circle around (2)} marked in FIG. 3E). Further, the file aging service server 300 may provide a cloud back-up function for the content according to a user opt-in, or a restore function for the deleted content.
Referring to FIG. 3F, the file aging service server 300 interworks with a system such as an enterprise resource planning server used in an enterprise, messengers and security programs to provide an environment which enables monitoring and lifecycle management of content ({circle around (1)} marked in FIG. 3F). For example, when staffs in an enterprise perform literary works or tasks, the file aging service server 300 may provide a timer function to set an extinction time of the relevant literary works ({circle around (2)} marked in FIG. 3F), and may enable an aging progress based on the lifecycle of the literary works, which has been created and distributed, to be recognized intuitively using a user interface element. Further, the file aging service server 300 may provide an environment to change or restore an effective lifecycle for content including the literary works ({circle around (3)} marked in FIG. 3G); provide a manager with an alerting service when changing the effective lifecycle contents including the literacy works; and provide a function that a manager enables the deletion of the content at his or her pleasure ({circle around (4)} marked in FIG. 3G).
In summary, the file aging service server 300 may receive the content storage event from the user terminal 100 via the content upload server 400 or directly receive the storage event from the user terminal 100. The file aging service server 300 may then map the extinction time included in the content storage event to the user terminal 100 to store a mapped result, and transmit to the user terminal 100 the extinction notice message of the content within a preset time period from the extinction time. Further, the file aging service server 300 may receive an answer message in response to the extinction notice message of the content from the user terminal 100, output the de-aging signal of the content when the answer message is the extinction rejuvenation message and transmit the content extinction signal to the user terminal 100 when the answer message is the extinction confirmation message of the content to delete the content.
Further details of the method for providing a file aging service illustrated in FIGS. 2 and 3A to 3G will not be described below since they are similar or identical to the description made through FIG. 1 or can be easily inferred from the description.
FIG. 4A to 4B are diagrams illustrating a data communication procedure performed among components in the file aging service providing system of FIG. 1 in accordance with an embodiment of the present invention. Hereinafter, while an example of a procedure to communicate signals in accordance with an embodiment of the present invention will be described with reference to FIG. 4A and FIG. 4B, the present invention will not be limited to this embodiment, and it will be apparent to those skilled in the art that the procedure to communicate signals as illustrated in FIG. 4 may be varied depending on various embodiments.
Referring to FIG. 4A and FIG. 4B, the user terminal 100 uploads content to the content upload server 400 at block S4100 and transmits the content upload event to the file aging service providing server 300 via the content upload server 400 at block S4200. The file aging service server 300 then maps the extinction time of the content to the user terminal and stores a mapped result at block S4300.
Next, the file aging service server 300 calculates a time difference between the extinction time of the content and a current time at block S4400, searches for a transformation degree mapped to the time difference at block S4500 and transmits the aging signal of the content based on the searched transformation degree to the content upload server 400 at block S4600. Accordingly, the content upload server 400 transforms the content based on the aging signal.
When the content upload server 400 transmits the search event to the file imaging service server 300, the file aging service providing server 300 changes the extinction time of content based on the search event at block S4830 and transmits the changed extinction time of the content to the content upload server 400 at block S4850.
In this case, the file aging service providing server 300 transmits the extinction notice message to the user terminal 100 when the current time is within the preset time period from the extinction time of the content at block S4910. Thereafter, upon receiving an answer message transmitted from the user terminal 100 at S4950, the file aging service server 300 analyzes the answer message at block S4970 and then transmits the de-aging signal or the content extinction signal to the content upload server 400 at block S4980. At this time, the content upload server 400 analyzes the de-aging signal or the extinction signal to carry out operations suitable for the respective signals at block S4990.
Further details of the method for providing a file aging service illustrated in FIG. 4A and FIG. 4B will not be described below since they are similar or identical to the description made through FIGS. 1. 2 and 3A to 3D or can be easily inferred from the description.
The order of the above operations described in blocks S4100 to S4990 is exemplary and the embodiment is not limited thereto. That is, the order of the operations described in blocks S4100 to S4990 may be mutually exchanged, and some of these operations may be simultaneously executed or partially removed.
FIG. 5 is a flow diagram illustrating a method for providing a file aging service in accordance an embodiment of the present invention. Referring to FIG. 5, the file aging service server receives the content upload event from the user terminal via the content upload server at block S5100.
Next, the file aging service server maps the extinction time of the content included in the content upload event to the user terminal and stores a mapped result at block S5200.
The file aging service server outputs the aging signal of the content, which allows transforming the content, based on a time difference between the extinction time and a current time at block S5300.
The file aging service server transmits the extinction notice message to the user terminal within a preset time period from the extinction time at block S5400.
Further details of the method for providing a file aging service illustrated in FIG. 5 will not be described below since they are similar or identical to the description made through FIG. 1 to 4 or can be easily inferred from the description.
The method for the method for providing a file aging service of the embodiment described in FIG. 5 may be implemented in the form of recording media including instructions executable by a computer, such as applications or program modules that are executed by a computer.
