EMDeviceFingerprintTokenPolicy

Objective-C


@interface EMDeviceFingerprintTokenPolicy : NSObject

Swift

class EMDeviceFingerprintTokenPolicy : NSObject

This class is used to create device fingerprint source settings that are applied to a token when it is built.

  • Specifies if fingerprint data is checked before using them.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL failIfInvalid;

    Swift

    var failIfInvalid: Bool { get }

  • List for device fingerprint source to use.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly) EMDeviceFingerprintSource *deviceFingerprintSource;

    Swift

    @NSCopying var deviceFingerprintSource: EMDeviceFingerprintSource! { get }

  • Default device fingerprint token policy source settings, with check enabled.

    Declaration

    Objective-C

    + (id)defaultDeviceFingerprintTokenPolicy;

    Swift

    class func defaultDeviceFingerprintTokenPolicy() -> Any!

    Return Value

    An instance of EMDeviceFingerprintTokenPolicy.

  • Build a new device fingerprint token policy.

    Warning

    If aFailIfInvalid is set to YES, it still remains a probability of ½^16 that wrong device fingerprint data will not be detected.

    Declaration

    Objective-C

    - (id)initWithDeviceFingerprintSource:
          (EMDeviceFingerprintSource *)aDeviceFingerprintSource
                        failIfInvalid:(BOOL)aFailIfInvalid;

    Swift

    init!(deviceFingerprintSource aDeviceFingerprintSource: EMDeviceFingerprintSource!, failIfInvalid aFailIfInvalid: Bool)

    Parameters

    aDeviceFingerprintSource

    Device fingerprint source to collect.
    aFailIfInvalid

    Specify if anti-cloning data must be checked before instantiating the token. If YES, when a token is retrieved the token manager verifies if the anti-cloning matches a digest of the expected anti-cloning. If it does not match then an exception is thrown.

    Return Value

    An instance of EMDeviceFingerprintTokenPolicy.
