  • the image recognition unit 101 refers to, for example, the captured image and determines whether the mark attached to the upper left corner of the window (“*” mark in FIG. 11A) is a browser-specific mark.

For example, it is assumed that the image captured by the imaging unit 11 this time is the image illustrated in FIG. In this case, the image recognition unit 101 compares the image shown in FIG. 11A with the past browsing images stored in the storage unit 15, and calculates the similarity with each browsing image.

If the determination in step S78 is negative, that is, if there is no browse image with a similarity equal to or greater than the threshold, the process proceeds to step S80, and the control unit 17 converts the captured image stored temporarily into the past browse image. Is stored in the storage unit 15. Thereafter, the process returns to step S70.
  • the image captured this time shown in FIG. 11A has a similarity with a past browsing image as shown in FIG. 11B (an image when browsing the website of “Internet bank”) or more than a threshold value.
  • the determination in step S78 is positive, and the control unit 17 proceeds to step S82.
  • step S82 the control unit 17 uses the OCR unit 102 to compare the URL included in the captured image with the URL of the browsing image. It is assumed that the control unit 17 recognizes where the URL of the Web site is written in the browser. Therefore, the control unit 17 extracts the range in which the URL is described from the captured image and the browse image, and causes the OCR unit 102 to convert the text. Then, the control unit 17 compares the URLs converted into text. Note that the control unit 17 may compare the images in the URL portion using the image recognition unit 101.

  • the control unit 17 includes the URL included in the captured image captured by the imaging unit 11 and the URL included in the past browsing image stored in the storage unit 15. And whether or not the imaging unit 11 has captured information related to the past browsing image (whether the Web site viewed by the user and the Web site included in the past browsing image are the same) is determined. The user is warned according to the determination result. Thereby, it is possible to prevent the user from accessing a fake website (such as a phishing scam site) similar to a website browsed in the past at first glance.

  • control unit 17 appropriately stores the captured image captured using the imaging unit 11 in the storage unit 15 (S80). Thereby, it becomes possible to add the captured image used as the past browsing image to the memory
  • control unit 17 transmits to the PC 20 a determination result as to whether or not the Web site viewed by the user is the same as the Web site included in the past browsing image, and the PC 20 To warn the user. Thereby, it is possible to display a warning in an easy-to-understand manner at an appropriate position for the user who uses the PC 20.
