System, method, and recording medium for a bi-directional feed between electronic calendar and credit-card authorization unit

1. A fraud detection system comprising:

a calendar reading device configured to read calendar data of a calendar for a user;

a purchase detection device configured to detect an attempted purchase using a credit-card of the user; and

a risk detection device configured to detect a likelihood of fraud by calculating a risk based on the calendar data and data related to the attempted purchase,

wherein the risk detection device further determines a location of a user device at a time of the attempted purchase and updates the likelihood of fraud based on a distance of the user device from a location of the attempted purchase, and

wherein the risk detection device further determines an intended location of the user from the calendar data and updates the likelihood of fraud based on the intended location of the user and the location of the attempted purchase,

wherein a location of the purchase is graphically represented on the calendar.

2. The system of claim 1 , further comprising a calendar marking device configured to mark the calendar with a mark of the attempted purchase detected by the purchase detection device.

3. The system of claim 2 , wherein the mark includes data about the attempted purchase including a product or service purchased, a class of the product or the service purchased, a location of purchase, and data regarding a specific credit card used.

4. The system of claim 2 , wherein the mark includes at least one of a graphical representation of the purchase and a textual description of the purchase.

5. The system of claim 1 , further comprising a calendar marking device configured to mark the calendar with a first type of mark if the risk detection device detects the attempted purchase likely to be fraudulent and to mark the calendar with a second type of mark If the risk detection device detects the attempted purchase to be authorized.

6. The system of claim 1 , further comprising a calendar marking device configured to mark the calendar with a first type of mark when the attempted purchase is attempted and a second type of mark when the attempted purchase is completed.

7. The system of claim 1 , wherein the risk detection device includes a learning device configured to learn user purchase tendencies based on the calendar data and purchase data and configured to modify the risk calculated by the risk detection device.

8. The system of claim 1 , wherein the risk detection device includes a learning device configured to modify the risk calculated by the risk detection device based on a fraudulent purchase.

9. The system of claim 1 , wherein if the risk of the attempted purchase is greater than a threshold value, then the risk detection device labels the purchase as fraudulent.

10. The system of claim 1 , wherein the user inputs data to change the calculation of the risk by the risk detection device.

11. The system of claim 2 , further comprising a selecting device configured to select, by the user, the mark to label the purchase as fraudulent.

12. The system of claim 11 , wherein the risk detection device includes a learning device configured to learn user purchase tendencies based on the calendar data, purchase data, and the fraudulent purchase labeled by the selecting device and configured to modify the risk calculated by the risk detection device.

13. The system of claim 1 , wherein if the risk of the attempted purchase is greater than a threshold value, then the risk detection device labels the purchase as fraudulent, and

wherein the risk detection device includes a learning device configured to learn fraudulent purchases and update the threshold value based on detected fraudulent purchases.

14. The system of claim 1 , wherein the calendar reading device reads calendar data of a plurality of calendars for a plurality of users, and

wherein the risk detection device calculates the risk based on the calendar data of the plurality of calendars and the attempted purchase.

15. The system of claim 14 , wherein the risk detection device calculates the risk based on a proximity of a first user to a second user based on the calendar data of the first user and the second user.

16. The system of claim 14 , wherein if an amount of the attempted purchase is greater than a threshold purchase amount is set by the users, then the risk detection device calculates the risk based on a distance of a first user to a second user such that if the distance is greater than a predetermined value, the risk detection device labels the purchase as fraudulent.

17. The system of claim 2 , wherein the calendar marking device includes a planning device, configured to calculate at least one of a rate of fraudulent transactions, an amount spent on shopping, and expenditure per an amount of time based on the calendar data.

18. A non-transitory computer-readable recording medium recording a program for fraud detection, the program causing a computer to perform:

reading calendar data of a calendar for a user;

detecting an attempted purchase using a credit-card of the user;

detecting a likelihood of fraud by calculating a risk based on the calendar data and the attempted purchase;

determining a location of a user device at a time of the attempted purchase;

updating the likelihood of fraud based on a distance of the user device from a location of the attempted purchase;

determining an intended location of the user from the calendar data; and

updating the likelihood of fraud based on the intended location of the user and the location of the attempted purchase,

wherein a location of the purchase is graphically represented on the calendar.

19. A fraud detection method comprising:

reading, via a calendar reading device, calendar data of a calendar for a user;

detecting, via a purchase detection device, an attempted purchase using a credit-card of the user;

detecting, via a risk detection device, a likelihood of fraud by calculating a risk based on the calendar data and the attempted purchase;

determining, via the risk detection device, a location of a user device at a time of the attempted purchase;

updating, via the risk detection device, the likelihood of fraud based on a distance of the user device from a location of the attempted purchase;

determining, via the risk detection device, an intended location of the user from the calendar data; and

updating, via the risk detection device, the likelihood of fraud based on the intended location of the user and the location of the attempted purchase,

wherein a location of the purchase is graphically represented on the calendar.

20. The system of claim 1 , sending an alert to the user when the likelihood of fraud is detected which displays the calendar and the graphically represented location on the calendar.
