Embodiment 1

[0030] This embodiment provides a method for reducing financial transaction risks, which is applied to a system including a card reading chip and a financial IC card chip. Specifically, the financial IC card chip and the card reading chip can be packaged in different hardware devices, for example, respectively Packaged in a financial IC card and a card reading device; or, the financial IC card chip and the card reading chip are packaged in the same hardware device, for example, both are packaged in a financial IC card. Such as figure 1 As shown, the method includes:

[0031] Step S1, the card reading chip prepares to send to the data source of the financial IC card chip, and generates an application authentication ciphertext request including the data source sent to the financial IC card chip;

[0032] In this embodiment, the request to generate an application authentication ciphertext is specifically a request to generate an application authentication ciphertext in which the...

Embodiment 2

[0041] Such as figure 2 As shown, the present embodiment provides a method for reducing financial IC card transaction risks on the basis of Embodiment 1, including:

[0042] Step S11, the card reading chip is ready to be sent to the data source of the financial IC card chip;

[0043] Specifically, step S11 includes:

[0044] Step 1-1, the card reader chip obtains the default data element;

[0045] In this embodiment, the default data element specifically includes authorized amount, other amount, terminal country code, terminal verification result, transaction currency code, transaction date, transaction type and unpredictable number;

[0046] Step 1-2, the card reading chip splicing according to the default data elements to obtain the data source sent to the financial IC card chip;

[0047] In this embodiment, the card reading chip splices the authorized amount, other amounts, terminal country code, terminal verification result, transaction currency code, transaction date,...

Embodiment 3

[0087] Such as image 3 As shown, the present embodiment provides a method for reducing financial IC card transaction risks based on Embodiment 1 and Embodiment 2, and is applied to a system including a financial IC card chip, a card reader chip, a client and a card issuing bank authentication server, and the client It is a browser web page or an application program installed in a mobile terminal device such as a smart phone. The methods include:

[0088] Step 101, the client receives the user's transaction request and prompts the user to use a dynamic password for authentication;

[0089] Step 102, the card reading chip receives and generates a dynamic password request;

[0090] In this embodiment, the card-reading chip obtains the request for generating a dynamic password input by the user on the hardware device where the card-reading chip is located. For example, the hardware device where the card-reading chip is located is provided with physical buttons. Obtain the requ...

Abstract

The invention discloses a method and device for reducing the risk of a financial transaction. The method comprises the steps that a card reader chip prepares a data source to be sent to a financial ICchip, and a request for generating application authentication ciphertext including the data source is generated; the card reader chip sends the request for generating the application authentication ciphertext to the financial IC chip; the card reader chip receives response data, containing the application authentication ciphertext, returned by the financial IC chip; the card reader chip conductscompression, scrambling and conversion on the response data to obtain a dynamic password; the card reader chip outputs the dynamic password to complete the financial transaction. The method and devicehave the advantages that the transaction password can be prevented from being exposed in an unsafe environment in the process of using a financial IC for transactions, the transaction password is prevented from being leaked, the transaction risk is reduced, and the transaction security is improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for reducing financial transaction risks. Background technique [0002] With the continuous improvement of the financial industry's informatization level, the financial industry's requirements for security levels are also increasing. Major banks at home and abroad are rushing to launch financial IC cards to completely replace traditional magnetic stripe cards. Financial IC card, also known as chip bank card, is a bank card with a chip as the medium. The chip card has a large capacity and can store information such as keys, digital certificates, and fingerprints. After loading display technologies such as electronic paper, it can display electronic cash balances , transaction details and custom data of the issuing bank and other non-sensitive information. However, in the prior art, some transactions on the website or by telephone still require the user to p...
