One embodiment of the underlayer is a multilayer of a thermal barrier layer consisting essentially of MgO and TiO, and a seed layer containing MgO and nitrogen (N) directly on the thermal barrier layer, with the recording layer on and in contact with the seed layer. The interface between the thermal barrier layer and the seed layer contains Ti and N, some of which may be present as TiN to act as a diffusion barrier to prevent diffusion of the Ti into the recording layer. The Ti-containing thermal barrier layer has a higher thermal resistivity than the conventional MgO thermal barrier/seed layer and thus allows for reduced laser power to the recording layer while still achieving a high thermal gradient at the recording layer. |

Methods, media, apparatuses and computing devices of user data authorization based on blockchain
A method of user data authorization based on blockchain includes: storing, by a first application client, encrypted user data of user data in a blockchain database through a blockchain node, generating authorization information in response to a request of acquiring the user data by a second application client, and notifying the second application client to obtain the authorization information such that the second application client obtains the user data based on the encrypted user data and the authorization information. The encrypted user data is stored in the blockchain database such that the encrypted user data cannot be tampered with and a leak of real user data is prevented. The second application client obtains the user data based on the authorization information and the encrypted user data. |

System and method for routing data to authorized users based on security classification of data
A system for classifying a data item to communicate to authorized users extracts features from the data item, where the features comprise a responsibility feature and a sensitivity feature. The responsibility feature indicates a job responsibility associated with the data item. The sensitivity feature indicates a sensitivity level of the data item. The system determines, based on the responsibility feature, that the data item belongs to a particular responsibility class. The system determines, based on the sensitivity feature, that the data item belongs to a particular sensitivity class. The system determines whether a user to whom the data item is directed belongs to the particular responsibility class and sensitivity class to which the data item belongs. The system sends the data item to the user, if is it determined that the user belongs to the particular responsibility class and sensitivity class to which the data item belongs. |

Cryptographic memory ownership table for secure public cloud
A computer-readable medium comprises instructions that, when executed, cause a processor to execute an untrusted workload manager to manage execution of at least one guest workload. The instructions, when executed, also cause the processor to (i) receive a request from a guest workload managed by the untrusted workload manager to access a memory using a requested guest address; (ii) obtain, from the untrusted workload manager, a translated workload manager-provided hardware physical address to correspond to the requested guest address; (iii) determine whether a stored mapping exists for the translated workload manager-provided hardware physical address; (iv) in response to finding the stored mapping, determine whether a stored expected guest address from the stored mapping matches the requested guest address; and (v) if the stored expected guest address from the stored mapping matches the requested guest address, enable the guest workload to access contents of the translated workload-manager provided hardware physical address. |

Intrusion detection
Techniques are provided for intrusion detection on a computer system. In an example, a computer host device is configured to access data storage of the computer system via a communications network. It can be determined that the computer host device is behaving anomalously because a first current access by the computer host device to the data storage deviates from a second expected access by the computer host device to the data storage by more than a predefined amount. Then, in response to determining that the computer host device is behaving anomalously, the computer system can mitigate against the computer host device behaving anomalously. |

Bridge computing device control in local networks of interconnected devices
Systems, methods, and apparatus for using a message broker that implements a publish-subscribe messaging protocol to exchange messages between a remote server and a bridge computing device of a local network of interconnected devices are disclosed. In one example, a bridge computing devices transmits to a remote server, a provisioning request in response to achieving a power-on state. The server generates and transmits, to the bridge computing device, a provisioning response that includes information indicating a channel to which the remote server will publish messages and a channel to which the bridge computing device should publish messages. The bridge computing device subscribes to the channel the server will publish to, and the server subscribes to the channel the bridge computing device will publish to. Third-party computing devices may also subscribe and publish to the channels in order to receive and provide messages to the bridge computing device. |

Multi-dimensional malware analysis
There is disclosed in one example a computing apparatus, including: a hardware platform, including a processor, a memory, and a network interface; a bucketized reputation modifier table; and instructions encoded within the memory to instruct the processor to: perform a feature-based malware analysis of an object; assign the object a malware reputation according to the feature-based malware analysis; query and receive via the network interface a complementary score for a complementary property of the object; query the bucketized reputation modifier table according to the complementary score to receive a reputation modifier for the object; adjust the object's reputation according to the reputation modifier; and take a security action according to the adjusted reputation. |

Parallel processing for malware detection
Client devices detect malware based on a ruleset received from a security server. To evaluate a current ruleset, an administrative client device initiates a ruleset evaluation of the malware detection ruleset. A security server partitions stored malware samples into a group of evaluation lists based on an evaluation policy. The security server then creates scanning nodes on an evaluation server according to the evaluation policy. The scanning nodes scan the malware samples of the evaluation lists using the rulesets and associate each malware sample with a rule of the ruleset based on the detections, if any. The security server analyzes the associations and optimizes the ruleset and stored malware samples. The security server sends the optimized ruleset to client devices such that they more efficiently detect malware samples. |
