TrustDevice-iOS

A lightweight library for determining device uniqueness and risk identification.

Create a device identifier based on basic device information.

Will remain the same after uninstalling and reinstalling or clearing app data.

🪧Attention🪧：The functions of the basic version of github are relatively limited.

You can visit AWS Marketplace or TrustDecision to learn about our professional version.

Quick Start

1. Add Dependcy

TrustDecision is available through CocoaPods. To install it, simply add the following line to your Podfile:

# Podfile
pod 'TrustDecision', '1.5'

2. Get DeviceInfo

DeviceInfo contains device id, risk information and device details.

Objective-C

#import <TrustDecision/TDMobRisk.h>

TDMobRiskManager_t *manager = [TDMobRiskManager sharedManager];
NSMutableDictionary *options = [[NSMutableDictionary alloc] init];
[options setObject:^(NSDictionary *response) {
    // Response in sub-thread, do something with the response
    // Get DeviceId
    NSString *deviceId = response[@"device_id"];
    // Get DeviceRiskLabel
    NSDictionary *deviceRisk = response[@"device_risk_label"];
    // Get DeviceDetail
    NSDictionary *deviceDetail = response[@"device_detail"];
} forKey:@"callback"];
manager->initWithOptions(options);

Swift

import TrustDecision

var options = [String : NSObject]()
let responseCallback: ([String : Any])-> Void = { response in
    // Response in sub-thread, do something with the response
    // Get DeviceId
    let deviceId = response["device_id"]   
    // Get DeviceRiskLabel
    let deviceRisk = response["device_risk_label"]
    // Get DeviceDetail
    let deviceDetail = response["device_detail"]                                         
}
options["callback"] = unsafeBitCast(responseCallback as @convention(block) ([String : Any]) -> Void, to: AnyObject.self) as? NSObject
let manager = TDMobRiskManager.sharedManager()
manager?.pointee.initWithOptions(options)

Open Source Features

• Basic device ID, consistent when uninstalling applications and reinstalling
• Basic equipment information, which can be used for simple data analysis
• Basic risk identification ability

RiskLabel	Risk Description
jailbreak	Attackers will have higher privileges and can install many cheating software to affect the normal development of application business.
simulator	The simulator provides many simulation functions, which will affect the normal operation of applications, such as virtual positioning.
debug	Applications can be modified by attackers at will, and the program will return unexpected values.
