Abstract: The present disclosure discloses a method and device for invoking a JAVA card object. The method comprises: receiving, by a JCRE, a service request message transmitted by an application Applet1; acquiring, by the JCRE, interaction information between the Applet1 and the Applet2 according to an ID of the Applet1 and an ID of the Applet2; acquiring, by the JCRE, a trust degree between the Applet1 and the Applet2 according to the interaction information between the Applet1 and the Applet2, information about one interaction comprising service class information for this interaction and information about whether a service request task of the Applet1 succeeds after this interaction; and determining, by the JCRE, that the Applet1 invokes a shared interface service of the Applet2, when the trust degree reaches a trust degree threshold.

Abstract: A method comprising: A. forming a consortium blockchain network using domain network nodes and selecting committee members from top-level domain nodes; B. the committee member who received most votes packs the genesis block and generates a random number; C. the housekeeper having the same number as the random number packs the current block and generates a random number for selecting a next housekeeper to pack the next block, each block is approved by more than half of the committee members; D. during the duty cycle, each housekeeper takes turns packing blocks and generating random numbers and the process is repeated. If a block is not approved, the housekeeper with the next number is requested to repack the block; and E. the last random number generated by a housekeeper before the duty cycle ends is used to select the housekeeper to pack the first block of the next duty cycle.

Abstract: Provided are a method and a system for opening an account based on an eUICC. The method includes: receiving, by an eUICC remote management platform, an account opening request forwarded by an operator management platform and comprising a user number, an eUICC identification and information of a service to be opened; allocating an ICCID; sending to the operator management platform an authentication parameter allocation request including the ICCID and the user number and receiving authentication parameters comprising an IMSI and an authentication key serial number fed back by the operator management platform; generating a complete profile according to the authentication parameters and a pre-stored initial profile; sending account opening parameters to the operator management platform to enable the operator management platform to perform a generation processing of an account opening order; downloading a complete profile to the eUICC and activating the complete profile.

Abstract: Embodiments of the present disclosure disclose an identity authentication method and device. The method comprises: receiving, by an identity authentication server, an identity authentication request transmitted by a third-party platform; determining, according to the phone number, an ID of a first identity authentication client by searching a pre-stored correspondence; if the first identity authentication client is online, transmitting a user information request; transmitting an authentication success message to the third-party platform if a user information response carrying the user information is received and the user information is consistent with user information stored in the identity authentication server; or transmitting an authentication fail message to the third-party platform if the user information is inconsistent with user information stored in the identity authentication server, or if a user information response carrying the user information is not received.
