Abstract:

【Purpose/significance】The contactless false information fraud crimes are carried out frequently by means of telecom net⁃

work tools, leading to great losses for the people. How to prevent the spread of fraud information from the source, and accurately under⁃

stand the implementation path of fraud from the process, that is of great significance for the prevention and management of telecom

fraud.【Method/process】This study utilizes a mixed research paradigm. We first selected 60 fraud information templates from specific

cases of the National Anti-fraud Center to encode the information characteristics. Then we conducted an open interview with the po⁃

lice, and build the decoy mechanism of fraud information by questionnaire survey and ANCOVA.【Result/conclusion】After three

rounds of encoding, a total of 56 initial concepts, 8 categorical concepts, and 4 main categories were obtained. It was found that fraud

information exhibits certain characteristics in terms of information sources, information forms, information content, and information

emotions. Then, obtain the three psychological factors of trust, attraction and worry of victims in Phone fraud cases. And the results

found that there were significant differences in trust factors between authoritative, relevant, and professional groups, and significant dif⁃

ferences in attraction factors between additional information, profitability, and operability groups, and significant differences in worry

factors between severity and urgency groups. That means, different types of fraud information had different psychological effects on sus⁃

ceptible groups. And based on this, we further explained the deception mechanism model by S-O-R theory.
