Method, device, and system of detecting a lie of a user who inputs data
Method, device, and system of detecting a lie of a user who inputs data. A method includes monitoring input-unit gestures and interactions of a user that inputs data through an electronic device; and based on analysis of the input-unit gestures and interactions, determining that the user has inputted false data through the electronic device. A particular fillable field, or a particular question, are identified as having untrue input from the user. Optionally, spatial orientation data of the electronic device is taken into account in the determination process. Optionally, contextual analysis is utilized, to determine that the input-unit gestures and interactions reflect an attempt of the user to perform a beautifying modification of a data-item to his benefit.
1. A method comprising:
monitoring input-unit gestures and interactions of a user that inputs data through an electronic device towards a computerized system;
based on analysis of said input-unit gestures and interactions, determining that said user has inputted through said electronic device data that said user knows to be false in order to increase a benefit that said computerized system provides to said user;
wherein said analysis comprises:
(a1) presenting to said user a form having a plurality of data-entry fields, including therein a first data-entry field and a second data-entry field;
(a2) defining, via at least one of: (A) a set of pre-defined rules, (B) a lookup table,
that a particular type of changes to data, that is entered in said first data-entry field in accordance with pre-defined timing rules and pre-defined context rules, is to be handled as a beautifying correction which increases the benefit that said computerized system provides to said user;
(a3) defining, via at least one of: (A) said set of pre-defined rules, (B) said lookup table,
that a particular type of changes to data, that is entered in said second data-entry field in accordance with pre-defined timing rules and pre-defined context rules, is to be handled as a non-beautifying correction which does not increase the benefit that said computerized system provides to said user;
(b1) detecting that said user typed via a keyboard a first value into said first data-entry field, and then changed said first value to a first replacement value;
(b2) based on per-field definitions made in step (a2), and by taking into account at least a first context and a first timing in which step (b1) was performed, determining that changes that the user performed in step (b1) in the first data-entry field, are a beautifying correction that was performed by said user via said electronic device in order to increase the benefit that said computerized system provides to said user, and triggering a determination that the first replacement value is false;
(c1) detecting that said user typed via said keyboard a second value into said second data-entry field, and then changed said second value to a second replacement value;
(c2) based on per-field definitions made in step (a3), and by taking into account at least a second context and a second timing in which step (c1) was performed, determining that changes that the user performed in step (c1) in the second data-entry field, are a non-beautifying correction which does not trigger a determination that the second replacement value is false.
2. The method of claim 1 ,
wherein the method is implemented by a hardware processor which (i) does not have a-priori knowledge whether the first value is true or false and (ii) does not have a-priori knowledge whether the second value is true or false.
