ESI-MS via an electrokinetically pumped interface
An electrokinetically pumped sheath flow nanospray interface for capillary electrophoresis coupled to negative mode electrospray mass spectrometer is described. At this interface, application of an electric field generates electro-osmotic flow at the interior of a glass emitter having an orifice.

Boosted bitlines for storage cell programmed state verification in a memory array
In one aspect of programmed state verification in accordance with the present description, the voltage levels on bitlines of non-target storage cells are each boosted by applying a non-zero offset or delta value, ΔV, to the bitlines of non-target storage cells during a precharge subinterval. A bitline verification voltage applied to a bitline of a target storage cell causes the voltage of the bitline to ramp up from the boosted ΔV value. As a result, starting from an initial value which is the higher or boosted ΔV value, the bitline voltage ramps up more quickly during the precharge subinterval to the bitline verification voltage level to improve system performance. In addition, the bitline verification voltage applied to bitlines of target storage cells during the precharge subinterval, can be at a relatively high value to maintain the accuracy of program state verification. |

Process for collecting electronic protected health information without a login
An efficient and secure process by which users may enter sensitive information into an electronic information system. When information is required from a user, the electronic information system may be configured to generate a unique access link (uniform resource locator, or URL) for that user. The link may be sent to the user via electronic communication, such as a text message or email. When the user follows the link with a web browser, the system prompts the user to enter an additional piece of personal information that is not known to the general public. Once identity is verified, the user may be required to electronically sign agreements. The user is then prompted to enter the required information. This may allow a user to deposit sensitive information into the system without requiring the user to provide full login credentials. |

Dynamic shared data object masking
A shared database platform implements dynamic masking on data shared between users where specific data is masked, transformed, or otherwise modified based on preconfigured functions that are associated with user roles. The shared database platform can implement the masking at runtime dynamically in response to users requesting access to a database object that is associated with one or more masking policies. |

Systems and methods for encrypted container image management, deployment, and execution
A controller is provided to construct and run a container from one or more encrypted container images without persisting any decrypted data from the one or more encrypted container images to non-volatile storage at any time. The controller may retrieve a container image with encrypted first data and encrypted second data, and may store the container image to non-volatile storage of a particular node. The controller may construct a container by mounting the container image as part of an encrypted file system of the container. During runtime execution of the container, the encrypted first data may be extracted and decrypted from the file system in response to a file system request for the encrypted first data, and the decrypted first data may be entered into volatile storage of the particular node while the encrypted first data and the encrypted second data are retained on the non-volatile storage. |

Computational risk analysis and intermediation
Provided are mechanisms and processes for computational risk analysis and intermediation. Security practices information characterizing security measures in place at a first computing system may be received from the first computing system via a network. Computing services interaction information characterizing data transmitted from a second computing system to the first computing system may be received from the second computing system via the network. A processor may determine a risk profile for the first computing system based on the security practices information. Based on the risk profile and the computing services interaction information, the processor may then determine an estimate of the information security risk associated with transmitting the data from the second computing system to the first computing system. A risk assessment message including the estimate of the information security risk may be transmitted to the second computing system. |

Methods, mediums, and systems for establishing and using security questions
Exemplary embodiments relate to the secure storage of security questions through an immutable log, such as a blockchain. The security questions may be stored in a centralized location, accessible from an application or browser tab running on the user's device. When a security question is required, such as to perform a password reset on a website, the website may interact with the application or browser tab, which retrieves the question(s) from the blockchain. The user may enter their answers to the question(s), which may be hashed by the application or tab. The hashed answers may be entered into the original requesting website, which may verify with the blockchain that the correct answers have been provided. Thus, the requesting website sees neither the questions nor the answers. Additional security features may include logging requests for questions, so that a user can determine if a security question may have been compromised. |
