Augmenting Navigational Guidance By Incorporating Local Regulations In Effect, Victor Carbune, Matthew Sharifi

Defensive Publications Series

Users often use map applications to get directions to travel from one location to another. Sometimes, temporary local guidance from public authorities that is in effect at the time of travel may impact availability and use of specific transportation modes. Currently, users must already know of such short or long term guidance from local authorities or must seek it separately because it is typically not available within the map application that provides travel directions. This disclosure describes techniques to provide travel directions with routing options and optimization that are based on criteria other than distance and travel time. Such additional …

Sandboxing Files Downloaded Via A Web Browser, Santhosh Kumar Edukulla

Defensive Publications Series

When browsing the web, users often download various types of files that are saved directly to the user’s device. Such files can potentially contain malware or trigger the download of malicious software when opened, thus making users vulnerable to cyberattacks. Typical web browsers scan downloaded files for malware. However, such scans cannot detect malware in certain circumstances, e.g., new malware for which the signature is not known, large file size of the download, etc. This disclosure describes a sandbox environment for isolating files downloaded during web browsing and scanning such files for malware prior to being transferred to the device …

Mechanism To Protect Field Area Networks From Eapol Attack, Yajun Xia, Lele Zhang, Chuanwei Li, Li Zhao

Defensive Publications Series

A mechanism is proposed to protect mesh networks from Extensible Authentication Protocol over Local Area Network (EAPOL) attacks in following ways. A Field Network Director (FND) synchronizes a whitelist table to a mesh node periodically, allowing to the mesh node to filter EAPOL messages based on the whitelist table. Further, a supplicant can sign EAPOL messages with its private key, and then a relay node can filter the EAPOL messages base on the signature.

Efficient Algorithm For Generating Order Packing Recommendations, Jonathan Yue Shun Poon, Guorui Su

Defensive Publications Series

Packing an order in the most appropriately sized boxes can improve customer experience, reduce costs, and alleviate stress for the operator that packs the items into the boxes. Products to determine optimal packaging typically consider permutations of packing options and select one that likely minimizes total costs while preventing the likelihood of product damage. However, such products use algorithms where the runtime increases exponentially with the addition of a box or an item in the input, thus making them impractical for orders that require multiple boxes and items. Moreover, such products typically do not take merchant and product variations and …
