Secure erase for data corruption
Disclosed in some examples are systems, methods, memory devices, and machine readable mediums for a fast secure data destruction for NAND memory devices that renders data in a memory cell unreadable. Instead of going through all the erase phases, the memory device may remove sensitive data by performing only the pre-programming phase of the erase process. Thus, the NAND doesn't perform the second and third phases of the erase process. This is much faster and results in data that cannot be reconstructed. In some examples, because the erase pulse is not actually applied and because this is simply a programming operation, data may be rendered unreadable at a per-page level rather than a per-block level as in traditional erases. |

In one embodiment a method is provided comprising automatically creating a link graph comprising nodes representing webpages, links representing hyperlinks, and weights for each link representing a number of times a hyperlink associated with the respective link redirected the a user devices from a webpage associated with a first node connected to the link to a webpage associated with a second node connected to the link; and determining based on the link graph a programmatically expected path for a particular user, wherein the programmatically expected path identifies, at least, two or more webpages that the particular user is programmatically expected to visit and specifying a programmatically expected order at which the particular user will visit the webpages. |

Automatic data integration for performance measurement of multiple separate digital transmissions with continuous optimization
In one embodiment, a method includes obtaining, from a demand-side platform (DSP), impression data specifying service providers and consumer tokens representing consumers who have received digital impressions of a set of advertising campaigns. A set of tokenized claims data records related to a prescription of a product is then received from a database server. A result set of integrated measurement records specifying measured campaigns linking the tokenized claims data records with impression data associated with consumer tokens and/or service provider identifiers is further received from the database server. Aggregated analytics reports based on the integrated measurement records are generated and presented. A machine learning model may be trained using a training dataset comprising features selected from the impression data and tokenized claims data records, to predict bid values or other parameters for use in updating, optimizing or modifying operation of the DSP for the original campaign or for other campaigns. |

Attention metrics for attention applications
An attention application measures a user's attention focused on publisher content and advertisements to create an attention metric. Attention can be measured via hardware sensors or by user interactions with input/output hardware. A user attention metric profile can be used to modify content, content presentation, and/or match ads. Aggregate attention metrics can be used by publishers or third parties. Attention consumers may reward attention with a digital asset. A proof-of-attention can be made based on secure attention sensor hardware and/or a zero-knowledge proof. |

Delayed processing for over-delivery determination for content delivery system experimentation
A delayed grouping (batch) processing of previous campaign delivery pacing decisions and corresponding outcomes (deliveries) is used to configure a new auction experiment iteration. In the new iteration, a campaign that was previously over-delivered is classified as either (a) over-delivered due to incorrect pacing or (b) over-delivered due to auction experiment design. After the delayed processing, the new auction experiment iteration is conducted with a mitigating action taken on the previously over-delivered campaign if the campaign is classified as (b) over-delivered due to auction experiment design. For example, the mitigating action can include removing the campaign from a subsequent iteration of the experiment, or the experiment can be redesigned. By doing so, the over-delivery caused by the campaign due to the auction experiment design is avoided when performing the new auction experiment iteration. |

Advertising campaign to viewing device suitability matching
In one aspect, an example method includes (i) determining a first binary number assigned to a content-presentation device, with digits of the first binary number corresponding to respective segments of content-presentation devices; (ii) determining a second binary number assigned to an advertising campaign, with digits of the second binary number corresponding to the respective segments of content-presentative devices; (iii) comparing the first binary number and the second binary number; (iv) based on a result of the comparing, determining that the advertising campaign is valid for the content-presentation device; and (v) based on the determining that the advertising campaign is valid, causing supplemental content associated with the advertising campaign to be transmitted to the content-presentation device. |
