Abstract: The present invention relates to a method for synthesizing sinapoyl malate comprising the steps of (a) (i) reacting syringaldehyde with acetic acid anhydride and an alkali metal acetate; or (ii) reacting sinapinic acid with acetic acid anhydride, and (b) cleaving the anhydride of the acetyl protected reaction product of (a) by exposing to water and an aliphatic alcohol to form protected sinapinic acid, (c) esterifyinig the protected sinapinic acid by reacting with an alkyl protected carboxylic acid ester to form protected sinapoyl malate, and (d) reacting the protected sinapoyl malate with aqueous acid to yield sinapoyl malate.

Abstract: Systems and methods are provided for detecting discrepancies in information that is displayed to a user across different webpages of an online shopping system. User interaction with the online shopping system is simulated in one example to collect data relating to webpages of the online shopping system. The data is analyzed to identify relevant semantic blocks of data and compare the data in those blocks across webpages. In an additional example, source code for the webpages is analyzed using machine-learning systems, which are targeted based on the results of the user interaction simulation to identify problematic source code and correct associated issues.

Abstract: A data file decryption method, a decryption device and a data broadcasting system are disclosed, which are applied to a data broadcasting service. Among them, the data file decryption method includes the steps of: receiving the file delivery information which includes a data file identification and a key file identification corresponding to the data file; receiving the corresponding data file and key file according to the data file identification and the key file identification; and decrypting the data file according to the key file.
