Decision Type Scenarios Considered
Approval • Fraud Recovery for Approved Fraud Transaction
Referral • Fraud Incurred from approval after customer calls back on
soft decline
• Fraud incurred when merchant calls back
• Fraud recovery for frauds approved on customer call-back or
merchant call-back
Decline • Fraud incurred from approval after customer calls back
• Fraud Recovery for frauds approved on customer call back
1. Provide complete consideration of authorization decision life cycle
2. Essential variables in decision process
3. Provide better documentation of business logic and enhance logic to improve
maintainability

Fraud Competency - Decision Tools
1. Statistical / Artificial Intelligence Based Models
1. 1st Payment Default Model – Score to identify fraudsters amongst the 1st payment
defaulters
2. Early Behavior Models – Score to identify fraudsters based on the first 30 days of
transactions
3. Internet Fraud Model – Score to identify potential fraud amongst e-shoppers
4. Probability of Charge-off Model – Score to identify fraud account likely to go charge-off
5. Probability of Fraud Model – Score to identify the prospect likely to be fraud
2. Ad-hoc Fraud Behavior Reports
1. Phone Zip Mismatch Report
2. High Risk ZipCode Report
3. Unusual Transaction Report
3. Industry Wide Infrastructural Mechanisms
1. Verisign
2. Staying Secure
3. MasterCard PayPass®
4. RiskWise

Identity Fraud Model will have 3 attributes
Indicators of Identity Mis-Match
•High Risk Zip Codes
• Invalid Phone Numbers
• Incomplete application forms
Indicators of Profile Mis-Match
• Differences in information available from Credit Bureau and
Application
• High Risk Occupations
• Phone number & City Mis-match
Usage of High-Risk Channels
• Prefer online applications with instant credit access
• Multiple applications within short span
• Frequent Lost & Stolen cases registered

Key Milestones during Model Build
• Run the driver list
through various
statistical / machine
learning algorithms
to establish criticality
• Based on the
goodness-of-fit the
final algorithm &
candidate model is
selected
• Identify all the
potential drivers
and segment
them into fraud
influencers as
discussed earlier
• Defining the
candidate fraud
behaviors
• Evaluating the
impacts of each
behavior Defining

Adiyanth Analytics is being set up with a vision of supplying analytical capabilities to
organizations that would want to "compete and win" based on its Data-driven
Competitive Advantage. We intend to arm the clients with this capability through any
one of the 3 core approaches - Outsourcing, Data Solutions, Professional Services. We
focus on Information & Knowledge management services wishing to cater to market
segment that consists of :
 organizations that have experienced growth for at least 5 years resulting in a unique
culture, brand recall, appreciation and market expectations being at their peak.
 These organizations are now at cusp and are at risk of quickly slipping into “trough of
disillusionment”, or at best feared for, flattened slope of enlightenment from any
misstep.
 They are addressing the 3 key challenges of Information Economy, viz., Availability,
Accessibility & Affordability of "knowledge for decision making"
